Last week, we were asked about the guardrail at the entrance ramp from Dorsett/Midland to Lindbergh. After talking with our traffic experts, that curve is a little tight for tractor-trailers, so they regularly hit it. We are working with the county to get that fixed. Andrew Gates, MoDOT Communications
We just put the new signals in at Gravois and Cherokee/Tennessee, and they were swapped over yesterday We have to make sure that everything is operating correctly before we take the old signals down. Our contractor is supposed to replace any sidewalks and ramps they remove within a week, weather permitting. Andrew Gates, MoDOT Communications
There is work on the sidewalks as a part of the project to rebuild signals and resurface Gravois within the city this year, including in this area. If they didn't remove anything yet, it should be fixed in the course of the project (since their requirement to replace the sidewalk in a week countdown hasn't started.) The signal portion wraps up by late summer and the resurfacing by the end of the year. Thanks for the additional information. Andrew Gates, MoDOT Communications
Our crews will check this out!
There is the Kiener Plaza renovation occurring there as well as a traffic signal improvement project. The former (which includes pedestrian walkways outside of curb area) is nearing completion while the latter (curb to curb area) is just beginning.
Interstate shoulders typically don't get filled in when we do resurfacing jobs -- the intent of the resurface is to give a clean/smooth driving surface for the traveling public. Except for emergency stops (or emergency vehicles), shoulders are not used as much -- eliminating resurfacing the shoulder helps save money to use on the roadways. Andrew Gates, MoDOT Communications
We have recently made some signal timing changes at the Manchester and Lindbergh intersection to improve the traffic flow. Our traffic engineers have been monitoring the situation and have seen definite improvement in the traffic flow, although there are occasions where traffic does back up briefly for one cycle length. As far as the striping, we can have our striping crews check to see if they can refresh the striping. It will be restriped this summer with our annual striping. Andrew Gates, MoDOT Communications
There is traffic detection at the Gravois/Kingshighway signal. So, you may have been sitting/approaching Schollmeyer and saw the light turn green for the dual right turn lanes. Due to the amount of cars the traffic light might have gapped out (meaning the traffic detection didn’t detect any more cars and started turning to red). Any unused time that is not used on Kingshighway goes to Gravois; so you may have had to wait an extended period of time to get a green for the right turn. We continue to monitor this location and will get with the contractor to verify that all the detection is still functioning properly. According to our traffic engineers, that right turn is getting enough time to move numerous cars through. Andrew Gates, MoDOT COmmunications
You're welcome on behalf of the contractor who has been actively monitoring detour traffic around the area to mitigate the impact of the work being done in the Kingshighway & Forest Park Pkwy area.
Please call our Lighting division at 314-647-3111 and they will share contact information.
Are you talking about the work in Illinois? Or the work over the 3rd Street viaduct? We don't have a construction project underway on the westbound PSB, though we are starting work on the eastbound side (into Illinois) that will run into 2018. Andrew Gates, MoDOT Communications
The signal is not primarily detection based. it is timed; however, if the camera detects no vehicles waiting to make the turn, it will move to the next phase -- it isn't responsible for the signal to dwell on a green signal when there is no traffic waiting. We'll doublecheck the detection and signal timing. Andrew Gates, MoDOT Communications
This is a promising technology that St. Louis County is investigating. However, we to date haven't incorporated it in a project. David Wrone, St. Louis County
We're doing bridge maintenance on both the 3rd Street Viaduct (in both directions) and rebuilding the bridge over the railroad near Murdoch. The 3rd Street Viaduct will start up again when winter weather breaks -- probably in early March. Don't have a specific date for the other I-44 work to start, but it should be around then as well. Andrew Gates, MoDOT Communications
We'll have our traffic engineer take a look at the ramps and see if the signs should be changed. Andrew Gates, MoDOT Communications
Typically, these are replaced by our on-call contractor in the order in which they are received. I am checking with our engineer who oversees this work, and will share the info when I get a response. Andrew Gates, MoDOT Communications
I am checking with our maintenance team to see if this is something we are working on. If I hear something, I'll share it next week. Andrew Gates, MoDOT Communications
I believe they go on the uphill side, but I am checking with my design experts and will get back with you on a more definite answer when I get one. Andrew Gates, MoDOT Communications
