Our traffic engineers will take a look at this location. Is there a particular time of day that you have observed this as being an issue more than the others?
Our traffic engineers can revisit this intersection as we've already adjusted this signal several times due to the activity that you have noted traveling between I-55 and west of the highway.
It's really all about usage. We do visual surveys to see if pedestrians use the bridge; in addition, we typically have placed postage-paid cards and requested people to let us know if they are using the bridge. We did that with both the bridge on I-70 and the bridge at I-55. We got no returns from any individuals using the I-55 bridge from the postcard. During our visual survey (which lasted about a week), we had one individual use the bridge. We currently have the bridge closed (as it is unsafe to cross) and we have asked individuals to let us know if they used it (and were unable to do so as we had it closed). We have not gotten anything from any customers who use the bridge over I-55. When we did the same for the bridge at I-55, we saw a significant use during our visual survey and got a fairly significant return from the postage-paid cards. Andrew Gates, MoDOT Communications
I've asked our traffic engineer to take a look at this signal and see if they can make any timing improvements during the morning rush. Andrew Gates, MoDOT Communications
We have a project planned to do roadwork along Olive in this area in about two years. I've asked our maintenance team to check this and see if the issue is in the area the state maintains, and see what they can do. Andrew Gates, MoDOT Communciations
Litzinger is set to get detection as a part of the work underway at Lindbergh and Litzinger. Andrew Gates, MoDOT Communications
The structure on Big Bend will in fact be a concrete planting box. We're installing it at the request of the City of Maplewood. The city will be responsible for maintaining the structure. David Wrone, St. Louis County
Typically, the state sets the timing on most of the signals along its routes; there are a few exceptions where the county sets the timing; Signals are timed to give the roadway with the most traffic the most time (which is why we ask for direction and time of issue when someone raises a concern about signal timing). If you are traveling against the rush hour traffic, you will wait at more signals. In addition, signals are timed for the speed limit of the corridor. If you travel above the posted speed limit, you will also stop at more signals. Finally, signals where there are pedestrian facilities and no push buttons to activate those facilities do have to make sure that any pedestrians have an opportunity to cross. Municipalities do significantly contribute to setting the established speed limit through their areas -- usually through ordinance; however, we do share information from traffic studies and analysis of the roadway to advise them on the best speed limit based on the roadway conditions. In this case, since the intersections are so close, and the traffic at 366/McKenzie is so heavy, the signals between Mackenzie and Trianon Parkway run free (they don't use vehicle detection). I have asked our traffic team to take a look at your concern to see if they can make any improvements. Andrew Gates, MoDOT Communications
Yes, we have a resurfacing project set for next year. Andrew Gates, MoDOT Communications
I'll have to check with our Construction and Signals groups for information on the steel plates on Hanley and malfunctioning sensor on Patterson. I'll post an answer next week. David Wrone, St. Louis County
We are still on track to have the westbound lanes open by December on that project. We have inspectors out daily to make sure that the project is being constructed according to the plans and specifications set out for the contractor by the design. If something does not meet the specifications/standards, the contractor needs to fix it before we accept the project as complete. In this case, the design had too much reinforcing steel in the column for the concrete to adhere correctly. We are working to remedy that; however it is purely an aesthetic issue and doesn't impact the bridge structure at all. Andrew Gates, MoDOT Communications
I'll forward this to our signals group, and will post an answer in a future Road Crew. David Wrone, St. Louis County
