Ask the Road Crew

If you always find a traffic chokepoint, a new pothole has cropped or have other commuting issues, ask our experts from MoDOT, St. Louis and St. Louis County in our weekly Road Crew chat on Wednesday, Sept. 27, at 1 p.m.

  • STL City - With repairs underway to multiple Mississippi River bridges, Tucker Ave., particularly from Washington to Cass, is seeing higher than normal volumes. Could your staff please adjust the signal timing accordingly? A lot of people are waiting on Tucker for minimal cross traffic.
  • We will have our traffic engineers check on the timing along Tucker in the area you mentioned. There is a detour active through the PSB job that brings traffic westbound on Cass to Tucker for access to the Stan Musial bridge. Our evaluation will include how well we are also feeding that bridge from further south on Tucker as you described. Thanks for your feedback!
  • I-70 & Cave Springs interchange: Going eastbound on Mexico Rd, there is a signal with two left turn lanes at Cave Springs/Muegge Rd. After turning left, the next signal is a very short distance at Veteran's Memorial Parkway (the south service road). The next signal is at the exit & entrance ramps from/to EB I-70. If you would use the right left turn lane, you could end up in a dedicated lane providing access to EB I-70. If you would use the left left turn lane, you could use a lane marked at the third signal to either go straight ahead or go right after the traffic island to enter the left lane of the EB I-70 entrance ramp. The problem: The timing of this third light has changed over the last two weeks. Only about five cars are allowed to use that lane to either go straight or turn onto the on ramp. Cars wanting to turn right to enter the highway (me!) are now stopped at a red light to allow oncoming traffic to proceed. The question: Why? I realize that this is a long post, but I wanted to give as much information as possible to make it clear what I'm asking. Thanks for hosting these chats.
  • We are continuing to make timing changes at the I-70 interchange at Cave Springs due to the construction by the city of St. Charles on the far side of the interchange on Truman Parkway. The lane closures north of the north outer road have a significant impact on traffic moving through the interchange. We have passed your thoughts on to our traffic engineers to see if they can make any improvements. Andrew Gates, MoDOT Communications
  • I'll forward this to our signals group, and will post a reply as soon as I receive it. David Wrone, St. Louis County
  • St. Louis County - The lights on Clayton Road at St. Rita, Bellevue, and Demun need to be better coordinated. I'm not sure if this is done on purpose, but they are terribly out of sync and during non-peak times, Bellveue cycles at random with no cross traffic present. Thank you
  • Shortly after sun-rise next Tuesday morning (October 3, 2017), Musick Avenue will be closed from Meath Drive to Lavinia Drive in South County.

    The closure could be in effect as late as next April 1, and will allow a St. Louis County contractor to remove and replace a 70-year-old bridge that spans Sappington Creek approximately one-half mile north of Tesson Ferry Road.

    KCI Construction is the County’s contractor for this $837,000 project.

    Approximately 5,000 vehicles drive across the structure on an average week day. During the project, motorists can circumvent the closure by using Tesson Ferry, Baptist Church Road and Gravois.

    The new bridge will consist of two lanes (one lane in each direction), and a sidewalk that will feature a concrete wall to protect pedestrians from passing traffic. The existing bridge does not have a sidewalk. Like the existing bridge, the new bridge will be concrete.

    KCI is contractually obligated to complete the project and reopen the bridge by April 1, 2018. However, work could be finished – and the road reopened – before that date. David Wrone, St. Louis County
  • There is a yield sign causing confusion at the intersection of the I255 eastbound exit ramp and Telegraph Rd (hwy 231). The yield sign requires drivers in the rightmost lane of the exit ramp turning onto Telegraph Rd to yield their lane to drivers southbound on Telegraph turning right on Kinswood Ln.

    The problem is that many drivers turning south on Telegraph from that rightmost lane on the exit ramp think the yield sign means they are to yield to all southbound drivers on Telegraph in spite of the fact their lane continues on and does not require a merge at the yield sign. When those drivers stop instead of continuing on in their lane some drivers behind them will wait impatiently, but others attempt to go around them and then a bad situation gets even worse.

    A MODOT engineer told me they would add additional signage, but Gloria Brown the state representative checked on the progress and found those engineers had been reassigned to other projects, so nothing was done.
  • In talking with the traffic engineers for that area, it also appears that the yield is there for pedestrians who may be crossing the ramp. Nonetheless, that doesn't address the issues you shared. I have asked them to revisit the area and see what we may be able to do to make it clearer and perhaps reduce some frustration. Andrew Gates, MoDOT Communications
