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.
