Jarred by potholes? Curious about road construction? Ask the Road Crew, 1 p.m. Wednesday
Ask the experts from the Missouri Department of Transportation, St. Louis and St. Charles counties and St. Louis City your questions about highways and roads. The live chat starts at 1 p.m. on Wednesday.

could there be a flashing yellow left turn arrow installed on the traffic signal at southbound Rt. 141 at San Simeon Way? Many times subdivision residents are force to sit at a red light waiting to turn into the subdivision while there is no northbound traffic to wait for. Thanks! -
There are too many lanes on northbound 141 to safely have that signal become a flashing yellow -- MoDOT only puts flashing yellow left turn arrows on roadways where there are two or fewer lanes that the left turn has to cross. However, if you can share some more specific times when you see the backups with no northbound traffic, I can pass it along to our traffic team to review and see if they can make any tweaks to the signal timing.

MODOT maintenance request - WB Watson at Grant's Trail / Pardee Rd - there are two "No Right Turn On Red" signs that light up when the trail users have the ROW. The upper one, on the mast arm, is working fine; the one attached to a pole, on the right/north side of the road, before the trail, is not working properly. Thanks!

The stoplights on Olive between 270 and 170 are no longer synchronized in the morning. I am most commonly there between 7:30 and 8 am. When 64 was reconstructed the lights on Olive were linked together and timed. Now I hit red lights at Center Pkwy, New Ballas, Craig, and Mosley, at a minimum. In addition, the Office Pkwy N light that is very close to Craig is generally out of sync, it is green when Craig is red. So what happened? Will this be fixed, or has the synchronization permanently been removed?

We recently optimized that corridor along Olive -- signal corridors are optimized to limit the amount of times traffic moving at the speed limit stops along the corridor during peak traffic times. Primarily, that would be heading toward the interstates in the morning and heading away from them in the evening. However, due to the on-going construction at Lindbergh and Olive , some of the signal timings have been adjusted due to the extra traffic detouring around the closed Lindbergh ramps. I have shared your observations with our traffic team to see if they can make any adjustments. As a note, when I-64 was reconstructed, traffic on Olive was given significantly more time than traffic on the cross streets, due to the high numbers of vehicles using Olive (and other east-west roads) because the interstate was closed. That timing remained in place for some time after the interstate reopened -- since traffic levels on Olive then went down, it seemed like the flow of traffic was smoother.

Many thanks from Andrew for the response regarding Olive. A change was definitely noticeable sometime in the last few months. Whenever the construction at Lindberg is completed, however, I would suggest optimization be done again. Heaviest traffic in the mornings is normally from the interstates into the Bayer/Danforth Center complex near Lindberg. In the evenings, the heaviest traffic is from that point outward to 270 and 170.

It will probably be about three to five years before the entire corridor is optimized again. However, we have passed your observations along, and if you see sticking points along the corridor after the construction is done (or even now, if you see something that seems to slow down excessively), you can certainly pass them along, and we can ask our team to take a look at them. You are certainly correct that there is a large amount of traffic heading toward Bayer/Danforth. Andrew Gates, MoDOT Communications

They have to wait until the new surface cures for a couple weeks before they can put the final striping down. They are still out there working on the top layer of surface in some areas -- they can't place it if the pavement is wet or it has rained recently. It should be done soon, weather permitting.

We have several projects we are working on for Manchester. One (between Big Bend and Lindbergh) should be starting later this year, and a second (between Lindbergh and I-270) should be awarded and underway next year. We will be starting with sidewalk updates on both projects, and when the sidewalk work is done, we will be resurfacing the roadway. You can see more here: Manchester Road (Route 100) between Big Bend and Lindbergh | Missouri Department of Transportation (modot.org) and here: Route 100 (Manchester) resurfacing from Route 61/67 to I-270 | Missouri Department of Transportation (modot.org). At this time, we have no plans for any construction at I-64 and Big Bend. Andrew Gates, MoDOT Communications

Could you please check the traffic lights at Page and Ball/Westport Crossing? It CONSTANTLY has phantom triggers or perhaps its timed to do so. Often times its a phantom signal for the EB Page left turn onto Westport Crossing. I will see it cycle 2 or 3 times approaching from the West.

The ramp work should be complete by the end of the year, but the overall project will continue through 2023. You can see more here: Interchange | 39 North AgTech Innovation District (39northstl.com). Andrew Gates, MoDOT Communications
