Last week, one of the chatters asked about a situation at I-55 and Reavis Barracks Road, where two pedestrian poles that used to house the ped button and the walk/don't walk indicators are missing. I heard back from our signal team and they informed me that they have the signal bases on order, but we have been waiting for them to come in. I have asked our maintenance forces to make sure that the area remains safe for pedestrians by putting the appropriate warnings around the locations where the bases are missing.

Apparently, a couple of states have done this. I think that we should consider doing something similar. www.atlasobscura.com

We've seen similar discussions about the-- I don't anticipate that we will be doing that along any MoDOT roadways anytime soon. Andrew Gates, MoDOT Communications

SB/WB Gravois from Tucker backs up in the evening (5pm or so) because of the light at Russell. Sometimes the line of traffic to get off 44 is on the ramp. Since Gravois has way more traffic than Russell, is there a way to adjust the light timing that allows more cars to flow down Gravois towards 55/Shenandoah?

We'll pass this along to our signal team to take a look at the traffic flow here. Andrew Gates, MoDOT Communications

On EB Manchester, at Hanley and the new bridge over Deer Creek, the end of the concrete barrier separating the sidewalk from the travel lanes is already getting run over/beat to death by (apparently) semi trailers not having enough room to make their right turns. Since this was not designed correctly, what can be done, now, to "fix"/modify it so that it will function properly?

by Jimmy Z 2/22/2023 4:30:34 PM
Our construction team will take a look at this, but I'm told there may not be a lot that they can do -- it is a tight turn, but if the barrier weren't there, the semis might be driving over the pedestrian refuge or clipping the signal post. Andrew Gates, MoDOT Communications

I saw the news about work being done on 270 between Manchester and Ladue in the evening hours for the next few months. What all do you have planned?

by Scott 2/22/2023 5:27:36 PM
We have some bridge painting on I-64 over I-270 and some pavement repairs on the inside lanes of I-270. We do also have some work on the ramps from I-64 to I-270 heading north to prepare for another project to replace the bridges at Conway and Ladue. Andrew Gates, MoDOT Communications

I live out near Gravois Bluffs and utilize the Continuous Flow Intersection there. When you turn left from Summit to Hiway 30, the first few cars make the intermediate light going east, but the end of the line cars either run the light, or get stuck at an ill timed red light. Is it possible to extend the time 5 or 10 seconds to let everyone keep moving and not get stuck at the light? This light provides time for left turns to Gravois Bluff and seems to have excess time allotted.

by StLDave 2/22/2023 5:48:28 PM
What time are you seeing the issue with the turn from Summit to Route 30? Timing plans often change during the day based on the number of vehicles using each leg of the route. Andrew Gates, MoDOT Communications

by Andrew Gates, MoDOT 2/22/2023 5:48:28 PM
It is this way 24 hours a day. It is the secondary light.

by StLDave 2/22/2023 5:57:01 PM
I'll pass it to our traffic team to see what they may be able to do. Andrew Gates, MoDOT Communications

by Andrew Gates, MoDOT 2/22/2023 5:57:01 PM
Thanks for the repairs to the WB Manchester - to - Des Peres Road ramp!

by LakeSider 2/22/2023 6:09:08 PM
You are welcome. Andrew Gates, MoDOT Communications

I noticed a sign stating bridge work on the Boone Bridge, starting March 6. What work will be done? Will traffic lanes be restricted? Thanks!

by LakeSider 2/22/2023 6:23:30 PM
The westbound I-64 Boone bridge is tentatively scheduled for some migratory bird nest removal, a bridge washing (takes the remnants of any winter treatments off the bridge) followed by an inspection. You can expect one lane closed in either direction as they are doing all of this work-- that should be during off-peak traffic hours, though. Andrew Gates, MoDOT Communication

by Andrew Gates, MoDOT 2/22/2023 6:23:31 PM
And a question for the County, too: the work being done on Adams in Glendale, is it still on schedule and might you have an expected date on which the road will reopen? I know there was something underground that required replacement - why did it fail or become obsolete?

by Clayton Dave 2/22/2023 6:42:54 PM
A St. Louis County DOT contractor is replacing a deteriorated box culvert - a type of bridge - on Lockwood/Adams. We're still on schedule, and expect to have the road reopened sometime this spring. David Wrone, St. Louis County's Department of Transportation

In last week's chat, a motorist asked about a new entrance recently built off Laclede Groves Road, into Lutheran Senior Services' campus. This entrance is temporary, and was constructed as part of an MSD project. Once that project is complete, the entrance will be removed. David Wrone, St. Louis County's Department of Transportation

Mr. Gates, Thank you for the update on the pedestrian poles at I-55 and Reavis Barracks Road. The pavement on your right-of-way, right before it adjoins the county's right-of-way at Reavis Barracks needs attention. It's pretty pock marked. I know that you have the I-55 resurfacing project ongoing, so maybe you already plan to repave. I'd appreciate some pothole patching in the interim. Thank you.

by M 2/22/2023 7:13:09 PM
I'm pretty sure that Reavis Barracks isn't a part of the I-55 resurfacing project, but I'll share your observation with our maintenance team. Andrew Gates, MoDOT Communication

by Andrew Gates, MoDOT 2/22/2023 7:13:10 PM
Heading south on Hwy 61, there is a dangerous drop off on the left side right after merging onto I-64 that is begging for a guard rail before someone plummets down the side.....

by dloyet 2/22/2023 7:18:09 PM
I'll pass your observation along to our traffic team to take a look at and make sure all the necessary safety equipment is in place. We do have a project looking at this interchange currently in the early stages of development. Andrew Gates, MoDOT Communications

On SB Geyer Road, approaching the traffic signal at Gravois, in Sunset Hills, there's a three-headed arrow (on the pavement) indicating that turning left, going straight, or turning right is permitted, required and/or legal. What purpose is it intended to serve? goo.gl

by Jimmy Z 2/22/2023 7:21:25 PM
Geyer Road in this location is maintained by the municipality of Sunset Hills -- talking with our traffic team, they believe that this is to help drivers confirm their options as they enter into an intersection that is slightly skewed. Andrew Gates, MoDOT Communications

by Andrew Gates, MoDOT 2/22/2023 7:21:26 PM
What can be done about lights not bring schronized in several area. I mean get from one light and stop on next. Two specific hampton and 44 area in STL and Bryan and 364 in stc.

by Zaffi 2/22/2023 7:31:12 PM
Signals are generally optimized for a particular corridor, and we do that regularly. Optimizing signals means that our traffic teams evalute the levels of traffic, including the times that traffic levels are higher. Since there are many cross streets with higher volumes of traffic, this helps make travel along the corridor more fair. Optimization means that signal timing is set to minimize the number of times that traffic heading in the heaviest direction stops, as long as traffic travels at the posted speed limits. Due to safety concerns (i.e. trying to avoid traffic backing up into high-speed corridors), signals from the interstates or major highways are given priority. If you have specifics (what direction you are traveling on what roadway, and what time you are seeing a possible issue) we can pass them along to our traffic team to evaluate.

Traffic on Graham Road NB in Florissant backs up between the light at Northwest Hospital and 270 (or further) during the evening rush (around 4:30). This light seems to cycle far too many times to back up that many cars on Graham. Can it be looked at? Thanks!

by Joe - South City 2/22/2023 7:33:21 PM
We've observed this area several times, and are in regular contact with MoDOT, in response to similar reports about Graham/Hanley congestion. However, we're not seeing anything particularly unusual. This is a very heavily traveled artery, particularly during rush hour. However, we'll continue to monitor traffic flow here. David Wrone, St. Louis County's Department of Transportation

Marine Ave/Westport Plaza Drive from Glenmeade to Fee Fee (and probably further) is badly in need of repairs. Any Plans? Previous repaving of Marine stopped at Glenmeade and should have continued past Westport Plaza.

by Ron 2/22/2023 7:54:19 PM
Work is scheduled to begin this spring on our Westport Plaza Drive/Marine improvement project. We'll be improving this section of roadway - including removing and replacing the pavement - from Glenmeade Drive to Lackland. David Wrone, St. Louis County's Department of Transportation
