2) Is EB I-290 traffic no longer going to be able to access WB I-88?  With the industrial areas east of I-294 along IL 64 and US 20, I think it would be desirable to keep allowing this possible movement, unless there are plans to add an entrance from IL 64 or US 20 to SB I-294 that would allow these areas access to WB I-88 via I-294.

I believe EB I-290 to WB I-88 will be eliminated. And honestly, who cares? Is that movement really needed? The vast majority of the traffic does not make that move, and eliminating it will allow for much better traffic flow for the primary movements. The few who need to make that move can continue down to Cermak/22nd St and take it west to the Spring Road I-88 entrance in Oak Brook.

You'd be surprised at how many make that movement.  Anyway, it's a moot point as there's a slip ramp in there, slightly hidden by one of the big arrows.

How much ROW does ISTHA and IDOT have at that interchange?

And if ISTHA designed to build on unused IDOT ROW, would IDOT allow it to be built for interchange and roadway improvements?

There's a pretty significant number of people who make that movement because I-290 has those ramps to IL-64 and St. Charles Road.  People will get on at those two ramps and take I-290 south as a means to reach I-88 (and the return trip of course).

The new EOE / west bypass can take some load off as well (but I-290 is free and some people may use it to save some $).

It won't take any of the load off from St Charles or North Avenues.

It seems that it won't be. If you look at this screenshot from the presentation, you'll clearly see the split in the ramp from I-290 East, with one branch leading to to I-294 South and the other to I-88 West:



Here, the split is covered up by the arrow, as Brandon noted, but you can still see that the line representing the split is thicker in that area, which suggests that it is still there.



I'm not sure, though, how the three-dimensional geometry is going to work here. Which ramps are going to over or under the others? In my admittedly naive opinion, there doesn't seem to be that much space in the area to go up and down as needed.

As for I-39's "who cares" question, while I couldn't give the exact numbers, I can say that I make that movement fairly often, at least when I'm in town.

That's a lot of flyovers/underpassing for those proposed ramps, unless they wanna tear down that row of housing just west of 290

that split trucks / bus BS. That area can use VMS speed limits. and jack it up to 65-70 when I-294 work is done.  And make I-294 min speed 60 for all parts now!!!!!!!!

What tickets?  Most judges in Cook County throw out any ticket made out for under 70.  Hell, District 15 ISP don't stop anyone for under 75-80 on the tollways.

It's all about the $$$ generated from speeding tickets.

Last summer when there were still working on I-90 but with no active construction workers present, I remember on Saturday morning at 7 am while I was going eastbound on I-90 near Arlington heights road, I was in front of a unmarked state trooper going 70-75 mph.

He later cut me off going 80 mph or so.

Generally I don't think state troopers care too much about speeding so long as you're not cutting everyone off or going 100+. I believe they got rid of the quota system a few years back. I read somewhere that speeding tickets have dropped more than 40% since then.

I'm in favor of this increase, but it seems odd I-90 gets to go to 70 while most of the Tri-State is 60 to 65 north of O'Hare.  It could be that I-90 has less congestion (so far), but there have been a couple afternoons I've heard on the radio that westbound I-90 is getting a slow spot between Meacham and Roselle.

It's not nearly as congested as the Tri-State, plus the Tri-State still has some "narrow" sections under old overpasses, etc (though one could make a solid argument for 70 MPH probably North of Golf or Willow Roads). Also, with the widening on I-90, other than an occasional slow zone just West of I-290, which I have heard is minute compared to what it used to be, it really does move quite well. That choke-point that used to exist Westbound by the Devon Ave Toll Plaza has all but been eliminated with the widening (the idea to have the fifth auxiliary lane continue to the oasis was very smart). Honestly, from traveling on it today, the average flow of traffic was easily going 70-75, so it really would just make sense to have the speed limit reflect the modernized design.

I'm a big fan of that I-88/294 interchange project. The biggest choke point is the connection from I-290 east to I-88 West, with I-294 being a massive problem during peak travel time. I always thought finding a method to pull I-88 westbound traffic away from the main lines before merging traffic from I-290 would be the key. It appears they have found it; now they just have to negotiate the ultra-tight ROW.

A high speed flyover for I-294 North to I-290 West traffic will be great too, but the problem again will be ROW. I hope they can accept that ramp may have to be single lane.

Finally, if the Des Plaines Oasis to Elgin stretch of I-90 can handle 70 mph, go for it. That extra lane will make a huge difference.

When is it in the tollway's radar to finish their halfass job they did a decade ago and redo the overpasses?

Well, according to the bid schedule, they are scheduled to replace the Bradley Road bridge just north of the Lake Forest Oasis next year. Additionally, they will be replacing the 159th street (US 6) bridge on the southern Tri-State just north of the 163rd street plaza.

So at least that's a start.....

Looks like some of those patching on the mile-long bridge on 294 are gonna need to be redone, only a couple weeks old and they're ripped open again :rolleyes: Unless they were supposed to be temporary while they get the left two lanes done, they'll have to go back over the two right lanes again soon.

I don't think they are putting much effort into maintaining the mile long bridge since they know it will be completely rebuilt in about 3-4 years.
