With the design they chose, one isn't really necessary.

I always saw WB 74 to SB 57 (and the reciprocal) as the primary movements at that interchange, so I'm not sure where "I-39" goes calling it a non-essential movement.  That one's very essential.

For designs such as this, having flyovers in "opposite corners" works better operationally because the two remaining loop ramps don't have weave conflicts.  They probably went with this design because, as I noted above, WB-SB *IS* the big movement, so EB-NB gets a flyover by association in order to eliminate the weaves.


This is absolutely correct. W74 to S57 is the primary movement for two big reasons. The big one being that local Champaign / Urbana traffic uses the interstates to navigate around the cities. The second one being that traffic from Danville, IL and Indiana wanting to go to Decatur and Springfield have to go south on I-57 to get to I-72.

Actually it sounds like you're talking about E74 and S57??
Avatar is the last interesting highway I clinched.

When I was saying non-essential movements, I was primarily referring to EB I-74 to NB I-57. That one is not needed. 

They really should be constructing a flyover from NB I-57 to WB I-74. I'm shocked they are not.

They have to by default since the WB 74 from the shopping district to SB 57 is the most used and will get a high speed flyover ramp. With growth in Mahomet and Lake of the Woods due to families fleeing the dreadful CU public school system that EB 74 to NB 57 ramp may see much more traffic in the future as well as I always take that route myself when coming from Mahomet to get off at Olympian Ave as a shortcut to Meijer and the Prospect shopping district which is much faster to access from the north. SB 57 to EB 74 may seem to be heavy due to the university, but that traffic is really only on specific days at specific times, also much of it uses the EB remnant of I 72 rather than head into Urbana, especially Football traffic.

Construction has finally begun on this project. Cones for a couple miles along 57 and sometimes a state trooper checking speed as you approach. They have Bloomington Rd all diked up and appear to be building half the bridge at a time with traffic constricted to one lane across. Once all the bridges of the secondary routes are lengthened to accommodate the new traffic flow work on the new ramps and flyovers will begin.

Thread bump!

Plenty of work remaining but the flyovers are beginning to take shape
