Golden Glades Interchange Makeover 5

This is the fifth of several posts regarding a makeover of the current disorganised highway <b>mess</b> called the Golden Glades Interchange.  The changes planned by the State of Florida I have summarised in the previous post in this series, and the one before that.

The changes that I see need to be done are not included in the State's plan consist of supplying a limited-access, non-stop connector for the 826 Palmetto Expressway eastbound to the Florida Turnpike northbound, a similar connector from the Florida Turnpike southbound to I-95 northbound, another between I-95 southbound and the Florida Turnpike northbound, and a multilane connector between the 826 Palmetto Expressway and I-95 North. Also missing are a ground-level, interstate-quality connectior for the Florida Turnpike connector to the Turnpike Mainline northbound and a mainline priority for most of the traffic going from the Turnpike to points south.

So here is the first of four posts showing what changes will be made to the interchange, step-by-step, to get rid of those deficiencies.

Satellite view of my first addition to the Golden Glades Interchange.
The changes planned by the state are in golden-yellow, my changes in white and red-outlined pink.

The first additional change to be done will be to build a direct connector ramp from 826 eastbound to the Turnpike northbound. It will require the taking of three (or four) pieces of property on the south side of the NW 7th Ave Extension, entailing the removal of three businesses: a self-storage place, a roadside gasoline station and a warehouse which leases some of its space to a non-denominational church. Some property may need to be purchased from the owner of the abandoned hospital that contains the small business called Perfection Cubeoctahedron and the Lubavitcher academy next to it (parking lots only -- no buildings will need to be removed) It will also require the construction of two bridges, shown in pink, outlined with red.

The viaduct will be built at such a height so as to clear my last addition to the interchange: the I-495 Golden Glades Northside Connector viaduct upgrade. The height of the ramp will be about 40 to 50 feet, depending on the required height of the upgrade and the depth of the ramp deck (including support beams) over it.

Once this 270-degree loop ramp is built, the existing traffic-lighted intersection at the east end of the 826 Expressway, opposite the gas station, will be removed.

Golden Glades Interchange Makeover 4

Okay, it's been a long time since I posted an update on my Golden Glades Interchange Makeover. The last post had to do with the Interim stage of the State of Florida's planned changes to the interchange. Now I will show you the changes the State will do for its Ultimate build-out.

Florida DOT's Ultimate build-out.

I will point out the changes the state is planning on constructing for its Ultimate construction for the sprawling-yet-too-small, confusing interchange. I will go roughly west-to-east, i.e., left-to-right as I relate the State's proposed changes. Just describing these changes is confusing!

Key:

7: State Road 7 (SR-7).
9: State Road 9 (SR-9).
I-95: Interstate 95.
441: US Highway 441
826: State Road 826 (SR-826), a.k.a. Palmetto Expressway and NW 163rd St.

And here are the changes:

1. 826 (Palmetto Expressway): Build an H-O-T connector viaduct from a point about 3,000 feet west of the Turnpike Connector to the I-95 Express Lane viaduct.

2. Build a separate H-O-T lane along the Florida Turnpike Connector southbound to connect with the I-95 Express lanes.

3. Rebuild 9 and 441 in the area of the Golden Glades Park and Ride Lots in connection to the repurposing of the lots themselves and the unweaving of different and conflicting streams of traffic underneath the Turnpike Connector.

4. Repurpose and redevelop the Golden Glades Park-and-Ride Lots. The lot west of 441 will become a bus terminal with commuter parking, or "Multimodal Facility"; the other one into a truck stop, or "Truck and Travel Center." The improvements for each of both are not shown -- too much precision work with an imprecise tool: MS Paint! (PS I tried copying and pasting from FLDOT's PDF on the interchange but the drafting images don't copy, just thye background photos.)

5. Separate the weaving streams of traffic along the road carrying 441, 7 and 9 underneath the Turnpike Connector to eliminate dangerous crossing of traffic to and from the Turnpike from all other traffic to all points north and east.

6. Extend the Turnpike Connector southbound to merge into the I-95 further south on the Interstate, i.e., at the Biscayne canal, just off the photo.

7. Widen the Turnpike Mainline feed-in to and from 826 (NW 163rd St) between the NW 7th Avenue Extension and the on-ramp from I-95 southbound, including the bridge over the railroad tracks.

8. Add new ramps from the 441-7-9 highway to the I-95 northbound, US 441 northbound and 826 (NW 163 St) eastbound. This work includes the construction of two new bridges over the I-95 to replace the old one that will be torn down. Two of the ramps will duck under the 826 (NW 163rd St) bridge over the I-95.

9. Add a new off ramp from the I-95 to 826 (NW 163rd St) eastbound and 441-7 northbound. This ramp splits south of the two new bridges for the highway carrying 441-7-9.

10. Update the pavement and safety features to the I-95 Expressway.

11. Remodel or replace a section of the I-95 Express Lane viaduct and include ramps for a new connector viaduct to the planned 826 H-O-T lane.

12.  Rework the I-95 / 441 / 826 / ramp system within the interchange itself. This involves repaving and rebuilding roadways and relocate a certain ramp from 441-7 northbound to I-95 northbound, to eliminate a bad reverse curve that tucks underneath a bridge, which will be torn down.

13. Renovate or replace the 441 / SR 7 northbound overpass to accommodate ramp changes and the I-95 Express Lane viaduct changes.

14. Repave and remodel the surface streets (NW 163rd St and NW 2nd Ave) on the east side of the interchange, including.the traffic-lighted intersection.

Phew! That's quite a lot. You can get a PDF of the State's (STILL) planned changes to this ugly mess by googling "Florida DOT Golden Glades Interchange" or by clicking here.

Next I will show you what can come next so that motorists travelling east on the Palmetto Expressway won't have to stop at a red light to get to the Turnpike and motorists travelling south on the Turnpike won't have to do the same to get to I-95 North.

An Idea for an Advanced Notice Exit Sign 2

I told you all that I'd do something about those Sword of Damocles arrows. You know, the kind pointing down just so that they look like they could fall off any minute and land on your car, causing vehicle damage and even personal injury or death (if it pierces the roof or if the convertible top is down).

So I have a sign spanning the full width of the southbound tollway at this place:

Source: aaroads.org

And this is how I would have it for the present Florida's Turnpike Extension number (SR 821) with my suggested design for a tollway in Florida:

The purple denotes the main road's present TAGS ONLY /  TOLL-BY-PLATE status. I'm going by Route Number and not the goofy fact that it's the Florida Turnpike Extension from original mile marker 4 of the Turnpike itself and not the original endpoint like Massachusetts did for the Mass. Pike.

Note the arrows underneath and divided by a line from the main board like in Australia.

Now here what it would like if it were an interstate:

I picked I-991 for two reasons: first, the existing Turnpike mainline is SR 91 which would become I-91 South in my scheme; second, if you look at a map you'll find most of the state highways in Miami-Dade County are in the 900s series.

Feel free to comment!

An Idea for an Advanced Notice Exit Sign

This is for the Homestead Extension of Florida's Turnpike at the Richmond Heights exit going south. Here's the existing:

Source: AARoads.com

So I would like to suggest something up like this:

First, I changed the standard USA exit tab with a pictographic one like the kind they have in Spain. I put the street names met by the exit at the upper right-hand side like they do in Australia. The Route Marker is similar to those from some of my suggested route markers for Florida. And I added the name of the nearest established neighborhood and the name of the nearby public facility / tourist attraction.

All it's missing are those Sword of Damocles arrows. More on that later.

Golden Glades Interchange Makeover 3

Okay, today I'll show you what the State of Florida is planning to do to make over this bad interchange that's utterly constipated with over 400,000 cars (actually all manner of motor vehicles) a day. Again, I'll first show you what the existing bad intersection looks like:

It's a mess, innit? If you can't figure out how it works from the air or a map, it'll be more difficult to make sense of it while on the ground! There are anecdotes of people getting hopelessly lost in this motorway junction of two freeways, a tollway and six/seven other roads. One of these days there'll be legends of the lost Floridian, wandering through the intersection, getting lost, finding his way out on the wrong road, turniong around and going back in ad infinitum.

Well anyway back in 2014 the State Transportation Department did a study and came up with some solutions. Basically they figured a way to get State Route 826 Palmetto Exway EB to I-95 NB, improve the flow of the Turnpike SB to the Golden Glades park 'n' ride and onto I-95 into Miami, and a lot of minor improvements (some "improvements" I wouldn't call them that) for the near term. This is their "Interim" plan for the interchange. Then theyre going to bring in new High Occupancy/Toll Lanes from the Palmetto Expwy to the I-95 Express Lanes to and from Broward County. and an on-ramp from the Turnpike SB into I-95 Express Lane into Miami. This is their "Ultimate" intent for the motorway junction.

So here without further ado is the State's design for the "Interim" plan, or what I call Stage One:

Revised the layout to more accurately reflect the State of Florida's Interim concept plan.
Also so that the State's Ultimate concept plan will fit with even the slightest bit of accuracy! 

And here I show a simplified bird's eye view: The major widenings, the new roads and viaduct, and one of the reworked traffic lights are highlighted in Spanish Orange. The rest are just shown as-is for your ease of viewing.

Bird's-eye view of the Golden Glades interchange with major "Interim" changes planned by the State shown.

Showing ALL the roads that are going to be rebuilt by 2020 is just going to be too damn much!  And would fill this bird's-eye photo with clutter.

Note the major do-overs:

1.  New connector ramp from State Route 826 EB to I-95 NB (on viaduct).

2.  Expansion of the Turnpike Connector SB (which really should be the mainline due to the amount of traffic it carries) to I-95 into Miami. This is going to be at its widest five travel lanes and two breakdown lanes.

3.  Widening and increasing the turning radius of the ramp from S.R. 826 EB to I-95 NB.

4.  Reworking the traffic lighted intersection of NW 7th Ave Ext and the Turnpike on-ramp so there are two left-turn "doghouse" lanes from S.R. 826 EB to the Turnpike NB.

Next I'll show you the State's "Ultimate" plan and tell you what's missing (a few vital freeway-to-freeway/tollway connections and vice-versa without traffic lights) and see how I can fit my ideas for this rat's nest with their plans.

31 May 2016 UPDATE: Revised my "stage one" or the State's "Interim" layout image, second one from the top, for accuracy purposes and to fit their "Ultimate" layout in. 

2 JUNE 2016 UPDATE: Revised marking for the I-95 Express lanes to a smaller marker in a more obvious location.

Golden Glades Interchange Makeover 2

Updated 22 May 2016

Well I have an idea... make a Northside Connector direct from the Palmetto Expressway to I-95 North and call it I-495. Also make improvements to the end of the Turnpike and make it FL I-91. Basically it involves the construction of a new limited-access highway with three-quarters of a stack interchange at the intersection of the Palmetto and the Turnpike.

Bird's eye view. Looking Northeast. Turnpike runs from center-left to lower right, Palmetto is at lower left. I-95 runs up the right side, bottom to top. The Northside Connector with ramps in red runs from the Palmetto at lower left to I-95 at the top. Surface roads called NW 167 St 7th Ave Ext and US 441 North in yellow.

Plane eye's view. Turnpike & Turnpike Connector (FL I-91 TPK) and Palmetto/Northside Connector (I-495) both in blue. I-95 Express Toll Lanes viaduct in purple. Ramps in Red. Surface roads in yellow.

Here you can clearly see that the (new) FL I-91 TPK mainline here follows the bulk of the traffic to and from I-95 out of Miami. The I-495 Northside Connector follows the existing NW 167 St 7th Ave Extension on a viaduct beginning just east of the existing Turnpike - NW 167 St North Miami Beach connector. The existing surface road below is reconfigured as shown in yellow. The ramps are shown in red.

The are four high-level ramps; they carry traffic:

(1) From (I-95) FL I-91 TPK NB to I-495 Palmetto X-way WB
(2) From I-495 Palmetto Xway EB to FL I-91 TPK NB
(3) From FL I-91 TPK SB to I-495 Northside Connector EB (I-95 NB), and
(4) From (I-95 SB) I-495 Northside Connector WB to I-91 TPK NB.

There are also two high-capacity ground-level ramps:

(1) FL I-91 TPK SB to I-495 Palmetto X-way WB
(2) I-495 Palmetto X-way EB to FL I-91 TPK (I-95) SB

Plus there is a two-branched ramp to the Golden Glades Park-and-Ride from the FL I-91 TPK SB and the I-495 Palmetto X-way EB.

The existing interchange of the existing Rte. 826 overpass connecting the Turnpike to NW 167 ST Miami Beach is tweaked:

(1) There is an I-495 eastbound surface road turnoff for NW 167 St 7th Ave Ext and NW 7th Ave North, because you know how traffic backs up at a light.
(2) The existing ramp to NW 167 St Miami Beach is rebuilt so the surface road turnoff can pass underneath.
(3) The existing off-ramp from the Rte. 826 overpass is tweaked to accommodate a merge from the reconfigured NW 167 St 7th Ave Ext.
(4) The existing on-ramp from NW 167 St 7th Ave Ext to the FL I-91 TPK NB is tweaked to accommodate the new high-level ramp no. (4) above.
(5) The existing Rte. 826 overpass feed-in to the turnpike is tweaked to accommodate the new FL I-91 TPK mainline and high-level ramp no. (2) above.
(6) The existing ramp from the FL I-91 TPK SB to Rte. 826 EB is extended or relocated as necessary.

Other:

(1) The existing ramp from Rte. 9 / US 441 NB to FL I-91 TPK NB is tweaked and extended to provide access to the I-495 Palmetto X-way WB via the new high level ramp (1) thereto.
(2) The existing US 441 ramps from the Golden Glades Interchange mess at I-95 to NW 2nd Ave are rebuilt / regraded as necessary to accommodate the new round-a-bout.
(3) New slip ramps are included to connect the reconfigured NW 167 ST Ext and NW 7th Ave to the I-495 Northside Connector to and from I-95 (westbound off-ramp west of the round-about, eastbound on-ramp from and east of the round-a-bout).
(4) The existing quarter-cloverleaf from FL I-91 TPK NB to I-495 Palmetto X-way and the existing ramp from I-95 SB to the Rte. 826 overpass WB are done away with.

But the rest of the Golden Glades Interchange that sits on the south side of the railroad tracks, I have no idea how to disentangle it; it's such a mess of spaghetti!

22 May 2016 Update: A tweak on the ramps from the I-91 TPK SB to I-95 SB, I-495 SB, I-495 (95) NB, Rte. 826 EB, etc., would be to have the ramp to I-95 SB/Rte 495 WB/Golden Glades Park-and-Ride split off of the ramp to I-495 EB/Northside Connector instead from the ramp to Rte. 826 EB/North Miami Beach.

Of course, the state has its own ideas, with a design based on what they predict the Average Daily Traffic (ADT) will be in 2040.  Now thanks to climate change and the sea-level rise at Miami and its effects on the porous limerock-encased Biscayne Aquifer, the ADT at this interchange might be... exactly... zero!

So I don't expect my makeover to be built, either.

Golden Glades Interchange Makeover

If you look at a detailed map of Miami's Golden Glades interchange, it is a MESS! Some movements can't be done without going to a far end of the interchange and back through a loop and several weaves. Another movement involves waiting in a doghouse lane waiting for a traffic light to change.

And yet at the same time it looks so convoluted, where ten arteries - four of them expressways - come together at one point that it appears impossible to improve it without acquiring a LOT of property! Any ideas? Put it in the comment box and provide a link to a more detailed expression of your idea.

Thanks!

Miami-Dade Transit

***Revised and Expanded April 9, 2016****

This is quite a detour from the International Highway Makeover but there is more than one way of making over highways. For instance, you can alleviate the choked traffic on them by building... SUBWAYS! That's right, subways. Heavy rail rapid transit, whether underground in tunnels, depressed tracks in trenches, right on the ground surface, elevated on levees, or overhead on skyways, will alleviate traffic on surface highways once they are attractive enough and there are enough of them.

Originally the system was envisioned as two branches to the northwest, one branch to the west and one line to the south. Other extensions were also put on the table and thought about. Here's what Wikipedia has to say about all this:

One variation of the Orange Line extensions was for a continuation passed the current airport station instead of the 1984 ghost platform at Government Center.

From the beginning, the Metrorail was designed and envisioned to have more lines than the current two line system; however, the federally subsidized cost of the original line ended up over budget at $1.02 billion,^[9] after which ridership was much lower than expected. The proposed lines included:^[18]

• The 13.6 mi (21.9 km) Biscayne/Northeast Corridor following U.S. Route 1 (Biscayne Boulevard) from Government Center up to the Broward/Miami-Dade county line in Aventura.
• The 9.5 mi (15.3 km) North Corridor up NW 27 Avenue to the county line.
• The 17.2 mi (27.7 km) East–West Corridor from Government Center west to the Florida International University main campus in University Park, as well as east from Government Center to the Port of Miami.
• The 5.1 mi (8.2 km) BayLink from Historic Overtown/Lyric Theater station to South Beach, Miami Beach.

You can obtain a more in-depth discussion of the above and other extensions at this link here (30 Mb PDF).

Back in 2010 I found a map drawn up by someone from Miami and they had an idea for many extensions:




Credit: NOT KNOWN
Whoever came up with this give me a call-out!

I do not know what has happened to this jpeg image since Miami-Dade Transit officials pulled the east-west Orange Line extension past the Airport and the other Orange Line extension north past NW 79th Street off the table and opted only for the Earlington Heights-Miami Central Station Connector.



 

And here is my take on the extensions above map. Watch out - it's huge (10.2 Mb)!

My Modest Proposal.

 

 

I think the first priority should be to build the Royal Palm Line, or Green Line, down to Cutler Ridge, extend the King Orange Line from Earlington Heights out to the west end of Arthur Godfrey Road in Miami Beach, and begin the Gold Coast Line from Downtown Miami north to at least the Design District, or better yet, Biscayne Plaza. Second on the agenda should be the construction of the Port Deco (Blue) and Central (Red) Lines from the Airport via the Orange Bowl and NW 7th St to Government Center and at least Port of Miami East, the extension of the Gold Coast Line further north, and the extension of the Tri-Rail down to Tamiami Airport. Third would be the completion of the Port Deco Line to Beach 5th St, the start of construction on the King Orange / Central Lines to FIU Tamiami and the completion of the northern Gold Coast Line to and perhaps into Broward County. Fourth would be the extension of the Gold Coast Line down to Florida City (of course this could be done earlier since Miami-Dade County owns the right-of-way so construction will be cheap) and the construction of the Citrus Line from the Airport to Douglas Road. Last would be the extension of the Citrus Line north to Calder, because, well, look where it's going!

The best way to do this I think is to extend Miami-Dade's half-penny tax for rapid transit over Broward and Palm Beach Counties and give the money AND the Metrorail / Metromover system over to Tri-Rail since at least they haven't been notoriously conspicuous in political corruption AND they can build Metrorails in those two counties, too, with the money. Which they should.

So what do you think of it?  All other things being equal, do you Miami-Dade Countians think it's a good rail rapid transit plan?

Yes, I know Miami is doomed because of AGW. In fact, it's supposed to become uninhabitable long before the seawaters flood the county's interior and coastal zones due to their infiltration of the groundwater in the Biscayne Aquifer, which South Floridians use for their drinking water. One or two drinking water wells have already been put out of commission due to this.

Today, Florida.

Sea Turtle specialty plate.

No county name to deter criminal elements.

(Several years ago a couple renting a car in South Florida were robbed and killed.

The criminals figured it was a rental from the county it was registered in.)

Self-explanatory. Oo-rah!

This one has the name of the county it's from.

Rare these days.

More US Routes

This series can be used in part with the ones in my previous post, or without. I posted these in small size at The Great International Highway Makeover a while back.

Regular US Route.

US Alternate Route.

If this is too confusing, just use the previous and suffix it with 'A'.

US Business Loop.

US Route on Tollway.

:^) Purple can be used instead of Prussian Blue.

The first sign above could then be used on freeways.

US Truck Route.

US Historic Route - The Mother Road.

US Scenic Route (2di).

Road through the Cumberland Gap.

US Scenic Route (3di).

The Avenue that's known as AIA.

I'd extend it to Canada using David Sturm's idea, also endorsed by R.V. Droz.

Tomorrow I'll throw up some other ideas how to treat US Routes on Expressways (Freeways and Tollways).

US Routes on Expressway.

By Expressway I mean what "road geeks" call Freeway. They are for the non-Interstate highways that are fully-controlled access (no traffic lights or intersections, no driveways) that are up to interstate standards* or otherwise.  Here are some examples.

Route US 1, no tolls.

Various sections in New England, 

the Northeast, North Carolina and Florida. 

Where Route US 1 is a toll road:

Tobin Bridge, Boston; GWB Bridge, New York;

and Delaware River Bridge, Trenton NJ - Morrisville PA.

Small size shown here.

Route US 19 in Pinellas County, Florida,

and in Metro-North Atlanta, Georgia.

Small size shown here.

Route US 93 in Vegas.

Route US 101 in California.

Bud Schuster Freeway in PA.

Unless they use the scheme for US Route Interstates in my previous post.

* Interstate standards: 12-foot travel lanes, a full 10-foot right hand breakdown lane, full left hand breakdown land for highways three travel lanes or more in one direction, 16'-6" clearance underneath the overhead bridges (overcrossings and sign bridges), no more than 6 percent grade.. 

Still More Florida Signs.

This time they're for Florida expressways: freeways and turnpikes.

Freeways. 

Turnpikes.

There are other designs I have submitted to RV Droz's Great International Highway Makeover, but I don't like them as much. I think these are best.

More Florida Signs.

Here are some other signs, small versions of which can be seen at R. V. Droz's The Great International Highway Makeover Florida page.

The first three are one-digit, two-digit and three-digit signs that can be used for state highways of primary importance. The tourist-friendly colors used are azure blue and tropical sea green.

The grey fields represent sky, i.e., the signs are cut-out shapes, not rectangles.

Here we have a state secondary classification and I chose coral red, bright red, dull gold and white with a black border.

And at last we have the county roads ("Pasco" is misspelled. Sorry.) I have a two-tone blue, warning sign Spanish orange, and goldfinch yellow for better visibility especially at night, although Spanish orange is okay in full sunlight.

Come to think of it, white letters with black outline would work better on the primary state route markers above, too.
