The repaving work on I-270 between I-44 and I-55 is set to be finished by the end of the year. A surface's life span depends on many things, including the type of surface as well as the amount and type of traffic on that roadway. Typically, we desire at least a decade out of a new driving surface, but would, of course, prefer it less often as long as the surface is holding out and the roadway remains safe..

Our contract mowing crews are out and moving through the areas. Our primary focus in each area would be the interstate, followed by arterials such as 94. Crews are currently working on I-64 in that area, so I would expect this to be cut soon. Andrew Gates, MoDOT Communications
The actual construction on the bridge in Shrewbury should be completed by the end of the year, but we do have some resurfacing work at that area to cover the existing lane lines and give a clean surface that is scheduled for spring 2019. The bridge work between Kingshighway and Jefferson will continue through 2020. This winter we have a pedestrian bridge rebuild, and then next year we will do the same bridge work on the westbound side, shifting traffic to the eastbound lanes. Andrew Gates, MoDOT Communications
Last week, we had a chatter ask about what appeared to be concrete signal bases left from the Gravois project at Cherokee/Tennessee and Gravois. We did check into that; those are not the old signal bases from our project. They would have to be something the city would have to check into, and we have passed the information along to them. Andrew Gates, MoDOT Communciations
Although we would like to make improvements in this area, we do not have any conceptual plans laid out for this area. Right now, we are focusing mostly on taking care of the existing roadway system, based on our available funding, so it is unlikely that anything would happen here soon. Andrew Gates, MoDOT Communications
I believe we have made some adjustments on many of the roadways in the area that would see more traffic from the I-270 work over Fee Fee Creek. You don't say when you are seeing the quick green from Creve Coeur Mill -- is it during rush periods or overnight? I can pass it along to our traffic team to check out.

The signals on Forest Park Parkway between Grand & Kingshighway were re-optimized in November of '17 and there has been a noticeable increase in the quality of traffic signal progression. However, one major factor that sets Forest Park Parkway apart from other major arterials in the City is that its volumes are both heavy AND bi-directional throughout the day. Other arterials typically are weighted in one direction during the morning and another direction in the evening. Forest Park Parkway carries equal (and heavy) volumes in both directions, regardless of what rush period you are in. As a result, the signal progression can't be prioritized to the dominant direction like another arterial (limiting the number of stops in one direction in the morning and likewise in the other direction in the evening). We'll continue to monitor the coordination on this arterial as we do with the other arterials and look for opportunities for improvement.
We will look at the timing for Pershing & DeBaliviere on the weekends. The highest cycle length that road would have is 120 seconds total. Perhaps an equipment malfunction is to blame - such as vehicle detection that is not consistently registering presence at the approach, leading to delays.
I'll forward this to either Clayton or University City, since one of those two munis would be responsible for this street. St. Louis County maintains North and South but not Meramec. David Wrone, St. Louis County
I'll check with our signals group and post a reply either later in this chat or in next week's Road Crew. David Wrone, St. Louis County
We are working on making repairs to the I-64 ramps on MoDOT right of way. That should be finished tomorrow. Andrew Gates, MoDOT Communications
Typically, merging traffic (in this case on the S. Memorial Ramp from downtown) has to match the speed of traffic to merge in. When that is congested, obviously that can be a bit more challenging. However, courtesy should dictate that when an interstate is congested and traffic is trying to merge in, you should work to make space for that merging traffic. This sounds like it is more of an aggressive driver issue, but I will pass it along to the our city traffic team to see if there is anything further they can do. Andrew Gates, MoDOT Communications
