There is limited space on the bridge to provide more advance warning of this closure. Any additional information further back into Illinois might get confusing with the existing Illinois workz one before you get to the PSB. Two of the overhead signs on westbound I-64 before the closure have the correct lane arrow covered and there is a safe distance to see the upcoming channelizers and flashing arrow panel for the closure. When the bridge is congested, we encourage drivers to use the full open lane and merge like a zipper at the closure. Andrew Gates, MoDOT Communications
Although Illinois isn't on this chat, the PSB is a fairly common reference for the I-55/I-64 bridge over the Mississippi between St. Louis and Illinois. Most maps have it referenced as the PSB. Of course, that name is really the common name for the bridge -- officially is it the "Congressman William L. Clay Sr. Bridge." That doesn't fit very well on a construction sign or an overhead sign, either. Andrew Gates, MoDOT Communications
I have passed your concern along to our maintenance team. You may call in items like this around the clock to our customer service team at 275-1500 or 1-888-ASK-MODOT. Thanks! Andrew Gates, MoDOT Communications
Reasonrules -- for your first signal question about Kingshighway at Gravois -- we are currently working on updating several of the signals along Gravois -- this one included. As we go through the process of installing and updating the signals and the timing, there will be some hiccups. We have passed your observations on to the contractor who is working on the project. They should be making updates to the signal timing soon. By the way, you say mid-afternoon -- can you provide a more specific time to help them update the signals? Andrew Gates, MoDOT Communications
There is limited space on the bridge to provide more advance warning of this closure. Any additional information further back into Illinois might get confusing with the existing Illinois work zone before you get to the PSB. There are several signs on the bridge indicating the closure. During times of heavy congestion, like you mention, we encourage drivers to stay in the open lane and merge like a zipper at the closure. Traffic moves more efficiently than if everyone lines up in one lane and you have a long backup. Andrew Gates, MoDOT Communications
I'll have to run this information through our Site Plan Review Group, and will post information on the issues you've raised as soon as I hear back from them. (Site Plan Review approves work performed on our Right of Way.) David Wrone, St. Louis County
You are correct in that we currently have no plans to resurface the roadway, but we will pass your concerns along to our maintenance team to see if there is anything further they can do. Andrew Gates, MoDOT Communications
Last week, a Road Crew reader asked: "Have the lights on Hanley Rd at Clayton been changed? Morning rush hour used to fly through there but now traffic is backing up almost to Hanley and 40. Thanks!" Here's our reply, as submitted by our Signals team: We conducted an inspection of the traffic signal at the intersection of Hanley Road and Clayton Road. The results of our inspection revealed that this traffic signal is functioning properly and as programmed.
However, our observations revealed northbound traffic was backed up through the intersection for a signification portion of the AM peak period. Further observations revealed that the backup was originating from the signalized intersection of Hanley Road and Polo Drive-Wydown Boulevard, north of the signalized intersection of Hanley Road and Clayton Road.
This backup is due to the fact that the vehicle detection loops on Polo Drive at Hanley Road have been damaged and are not functioning properly. The City of Clayton’s Contractor recently damaged these vehicle detection loops during the repaving of Polo Drive. Since the vehicle detection loops were damaged and not operating, we had to put the Polo Drive signal phase on recall to provide a minimum GREEN time each signal cycle. Providing this minimum GREEN time means the Polo Drive signal phase will come up every cycle regardless of the traffic demand on this approach. Typically the Polo Drive signal phase is not actuated every cycle in the AM peak period and the time allotted to this signal phase is typically re-allocated back to Hanley Road. Therefore, until these vehicle detection loops are replaced, motorists on Hanley road will experience delays since their typical GREEN time has been reduced.
We are working with the city of Clayton to get this vehicle detection loop replaced as soon as possible. David Wrone, St. Louis County
Yes, we do plan to have a construction camera for the Route 47 bridge. At this time, we don't have a specific time when it will be put out there. Andrew Gates, MoDOT Communications
Our signal crew is checking this out - thanks!
The intersection of Gravois and Kingshighway is MoDOT-controlled. As for the intersection of Morganford and Robert, there is vehicle and pedestrian detection installed wherein the signal should only cycle to the side street when activity is present. We will investigate to see if either is malfunctioning.
Please see the response below on Gravois at Kingshighway. Thanks! Andrew Gates, MoDOT Communications
Yes, we still have guard rail that needs to be installed along eastbound I-64. We expect that to be done in about two weeks, weather permitting. Fencing should be reinstalled. Andrew Gates, MoDOT Communications
It would not have been advisable to make a northbound right turn from the westernmost through lane as the easternmost lane is also a through lane across the intersection - though I can see why you would want to with the east lane queued waiting to turn. I'm aware of the influx at that time, but is the queuing usually as bad as today's?
We are working with MoDOT to come up with a plan to address your concerns as they control the I-64 signal and we control Oakland.
Our street crews will investigate - thanks!
At this time, we have no funding or current plans to make any changes at the ramp from northbound Riverview to eastbound I-270. However, we are currently working on a study of the northern portion of the I-270 corridor (from McDonnell to the river) and Illinois is working on a study that may replace some or all of the Mississippi River Bridge there. Although it will be some years before IDOT finds funding and starts construction for a new bridge, that project may include some improvements at the Riverview entrance. Andrew Gates, MoDOT Communications
I've passed it along to our signal team. Andrew Gates, MoDOT Communications
Street lights should be back to normal operation tonight!
These lights were installed as lane use control signals to identify when a lane was blocked due to a crash or a stall. Technology has advance and in lieu of operating these signals that are difficult to maintain, we have instead used our large shoulder mounted dynamic message signs that allow us to communicate with motorists. The dynamic message signs allow us to tell the motorists what is closed, where it is closed and what action should be taken. In the future instead of posting messages on dynamic message signs, you may receive the same message on your cars dashboard. Andrew Gates, MoDOT Communciations
The City owns and operates Arsenal & Ivanhoe. Both intersections have vehicle detection installed and we will investigate if it is malfunctioning.
I've asked my maintenance team if they have any insight. I haven't heard back from them yet, so I will share any response I get during next week's chat. Andrew Gates, MoDOT Communications
That turn maneuver is allowed as the northernmost lane is a shared through/right lane while the southernmost lane is right turn only. Additional tiger tracks and possibly signage could be added to further clarify this to motorists.
