Thanks for the kudos. I'll pass them along to the team overseeing the resurfacing project. Andrew Gates, MoDOT Communications
That was one of the questions looked at during the 21st Century Missouri Transportation System Task Force. A major concern expressed to that task force was that counties wouldn't have the available funding to maintain those roads effectively. You can see the task force report here: https://house.mo.gov/billtracking/bills181/commit/rpt1723/Transportation.pdf. You can also look at the Statewide Transportation Improvement Program to see where funds are being spent (including those on lettered routes): https://www.modot.org/statewide-transportation-improvement-program-stip.

We're currently waiting for our contractor's repaving crew to complete work unrelated to this project. We anticipate a late June/early July start time on the resurfacing of Big Bend (from Clayton Road north to Delmar). David Wrone, St. Louis County's Department of Transportation
We do maintain a small fleet of sweepers. However, we don't use them to remove piles of yard waste (leaves, sticks, sweetgum balls, etc.) from the roadway. Missouri law requires that this category of debris be segregated from other waste, such as the fast food wrappers, cans, sacks, etc., and separately landfilled. We we simply don't have the resources to accommodate that edict. Our sweeper operators will maneuver their machines around any human-deposited mounds of yard waste they encounter. If your subdivision has non-yard waste debris issues on its streets, please call our Service Request line at 314-615-8538, and we'll schedule a sweeper ASAP.

Unfortunately, signage often doesn't encourage drivers to slow down -- that would need to be addressed by local law enforcement; however, I did ask our traffic team to check and make sure that all the appropriate signing is in place. I have asked our maintenance team to check out the potholes you mention. Andrew Gates, MoDOT Communications

We did a resurfacing job on Route 30 in that area a couple of years ago. During that project we updated sidewalks to meet Americans with Disabilities Act requirements, and made a few connections that were highly traveled. There are several areas where there is a sidewalk on one side of the road, but not the other -- due to available shoulder space, entrances and grades that make it impractical to install sidewalks. We do have a project that is supposed to update signals at Sappington Rd., Route P (Mackenzie) , Elgin Ave/ Weber Rd., and Seibert Ave soon. As a part of that, we make sure the sidewalks at those intersections meet ADA requirements. We have no further work currently planned for Route 30 in that area. As development continues in that area, we will definitely encourage developers to consider tying into existing sidewalks, and when we next have a project on Route 30, we would take a look at if there are additional areas where it makes sense to add sidewalks.

There are numerous sections of Big Bend that are not under St. Louis County's maintenance. These sections are located near interstate highways, and are in MoDOT right of way. Re: the End/Beginning of Maintenance signs: these are installed as a public service, and offer motorists who wish to report a problem real time information about what we do and don't maintain. David Wrone, St. Louis County's Department of Transportation
It looks like that should be should be starting in June -- based on availability of the paving contractor. Andrew Gates, MoDOT communications
The timing on Jefferson is set up to progress traffic in the PM rush predominately southbound, but the platoon of traffic begins further north of Market. There might be a slight delay for you as noted if you're starting southbound at beginning of green from Market, but the majority of the platoon of traffic that starts north of you will arrive after you while green has been active at Hwy 40 to allow some queue clearance prior to arrival.
We have some pavement repairs scheduled for the approach on the bridge that you mention. Andrew Gates, MoDOT Communications
