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

Ah! You beat me to it. I saw this yesterday.

The flyover from W 74 to S 57 has all its girders placed along with the two bridges from W 74 to N 57 They finished a couple weeks ago, but no work seems to have begun yet on placing the steel girders on the pylons on E 74 to N 57? Maybe they will need to reposition all those cranes and are waiting to finish the two new halves of the mainline 74 bridge over 57 so they can tear down and place the beams for the other half where the old highway now carries traffic? All I know is it sure took a lot of time, in China I know each of the two flyovers would probably have two teams starting from each end and the whole thing would have been laid out in a few weeks. Erosion is also really starting to carve these furrows into the sides of the raised earthworks for all the ramps and grass definitely needs to be planted ASAP to stabilize the things. I haven't seen the photo radar camera speed trap van since late 2022 so it seems to have been a reaction to the accident that happened on NB 57 in the fall of 2022. I do see ordinary State Police writing tickets on the NB and SB 57 fairly often as I pass through here daily yet somehow still see semis blazing through in the 45 speed zone at nearly 70 in the left lanes.

Yeah but who the hell would rather live in China than Illinois?

I hate IDiOT for constructing those damn cloverleafs at all-Interstate junctions. Here's hoping more replacements will come in the future.

OK, well I could also say the Eisenhower would also have gotten in done a lot faster. It's not "slave labor" but the legalism with endless "studies" and "permits" needed to get the thing going and just the economic malaise that deems it better for one crew to get 5 years of work out of it by going slow rather than a bunch of teams getting it done quickly then off the the unemployment office because Illinois is largely dead economically. We are supposed to be getting a new H-Mart in the old County Market building in downtown Urbana. However it is taking absolutely forever and the excuse given is that the "permitting" is the hold up. One thing for sure, H-Mart's have nice, inexpensive food courts in them where you can get restaurant quality food cooked without dealing with all that sit down table and menu, tip, waiting, etc. that caused an entire fast food industry to spring up in the mid 20th century to bypass that had the drawback however of offering little more than junk food until the next wave of Chipotle type business models have begun to replace the fried potatoes and burgers with something a bit more fulfilling.

Well then praise mid-20th Century America's capacity to get things done from the first word.  Why bring up China at all?  You were asking for that kind of response.
