We are wrapping up construction on a lot of signal work along Gravois. The contractor is supposed to work on optimizing the flow of traffic along Gravois, starting in mid-August. The challenge here is that there are still several signals on that corridor that need to be replaced (adding detection and pedestrian buttons). Those are not scheduled to be replaced until 2018 (due to available funding). We have passed your observations along to our contractor team and will continue to monitor the roadway and make adjustments along Gravois. Andrew Gates, MoDOT Communications
I have asked our maintenance team to check out the pavement (MoDOT maintains the roadway there). Andrew Gates, MoDOT Communications
Thanks -- I have shared that with our signal team to check out the equipment and make sure it is working. Andrew Gates, MoDOT Communications
The River Des Peres Greenway project along Wabash/Ellendale was made possible through a federal grant with a 20% local match. Hampton, between Oakland and Wilson, will be paved in July through aldermanic improvement funds.
When did you observe problems on Kingshighway? Those closely spaced lights are tightly timed together to progress folks through that area. We haven't had any complaints about it recently.
What intersection so we can check it out?
Last week, a Road Crew participant reported recent traffic congestion on northbound Big Bend, approaching I-64/40, and asked us to check the signals at that intersection. We did so, and although the signals were determined to be functioning properly, we learned that the Richmond Heights Fire Department preempted the traffic signal at Big Bend Boulevard and Dale Avenue, immediately south of I-64, several times during the morning peak period, between June 5 and June 14, 2017.
When the traffic signal at Big Bend Boulevard and Dale Avenue is preempted for an emergency vehicle leaving the Richmond Heights Fire Station on Dale Avenue, the coordinated flow of traffic along both northbound and southbound Big Bend Boulevard is detrimentally affected. This preemption can lead to the congestion and backups to which the reader alluded last week. David Wrone, St. Louis County
Paving is still to occur now that ramps are done - that will fill the area around them to transition appropriately.
Thanks - we will check it out!
That is a good philosophical question, and one that I am sure that you would get as many answers as you have traffic experts looking at it. Ideally, the roadway with the most traffic should get the most signal time, so one might expect to stop regularly at cross streets with high levels of traffic. We try to optimize corridors -- such that as one travels, at the speed limit, down the corridor, one limits (but does not eliminate) stopping at red lights. The challenge, as I said, on Gravois, is the mix of signals that have detection and older signals that require a set timing plan (because of lack of ped signals, etc). Until we are able to replace the remaining signals along the corridor, you may find that one signal (that has detection) turns green early because there is no traffic from the streets feeding onto Gravois, and then you get stopped at a signal that has to have timing.

I'm unclear about the recent St. Louis County Road Crew reply to which you're referring. We recently restriped a section of Big Bend, but the work had nothing to do with bicycle lanes. In fact, I can't recall fielding any bike lane questions on this forum in recent months. David Wrone, St. Louis County
We have a mix of old and new cameras along our corridors, some analog, or some that were designed for older software. It may also depend, to a certain extent, upon the browser that you use -- I have noticed more success with camera views on Internet Explorer than with Firefox. We are looking at making some updates to the Gateway Guide website to make it a bit more mobile friendly, and should be rolling them out soon. Andrew Gates, MoDOT Communciations
I have shared this with our maintenance team as well; however, there is a big difference between the tools and equipment required for roadway patching and that needed to removing and replacing rough patches. I'll let you know what I find out. Andrew Gates, MoDOT Communications
There are several signs leading up to the construction along I-64 --I have asked our construction team to take a look and see if they can do anything else that might help during those times when eastbound I-64 backs up. Andrew Gates, MoDOT Communications
No, the small yield sign at the offramp is in place for bikes to yield to oncoming traffic. The vehicles on the on-ramp have a yield to pedestrian sign before the cross walk. We are still putting up signs along Gravois with the resurfacing project, and so the signs indicating that the bike lane ends should be installed before the end of the project this year. Andrew Gates, MoDOT Communications
We are expecting the current resurfacing on I-270 between Route 364 and ultimately I-55 to last between 10-15 years. Andrew Gates, MoDOT Communciations
Yes, we are responsible for the signal at Chouteau and Jefferson. We work closely with the city to monitor and adjust timing between our signals and theirs. Both Chouteau and Jefferson have a lot of traffic. We need to be able to give time to both movements -- there is simply more traffic at this intersection than it can handle. If we take time away from Chouteau to give to Jefferson, Chouteau will start to back up. We are working with the city to make some other improvements along Jefferson in the future. We will continue to monitor our intersections along Jefferson and make what adjustments we can. Andrew Gates, MoDOT Communications
I'll check with our Operations Division, and post a reply for you next week. Thank you for sharing your views. David Wrone, St. Louis County
I have asked our traffic team to weigh in. I will share what they have to say next week. Andrew Gates, MoDOT Communications
I believe that section of Hampton will be paved next year in order to spread out the cost between two fiscal years.
I am waiting to hear more back from our traffic engineer here. If I get some info, I'll share it. However, looking at the ramp, drivers on the ramp from the interstate have their own lane -- so Gravois traffic would not have to yield to the cars in the off-ramp -- but if Gravois traffic wanted to move into that lane (which, in essence, a cyclist would have to do), they would have to yield to traffic in the lane. As a note, it is probably safer as well -- having a driver on the ramp looking almost behind them to see if a cyclist is coming while trying to get onto Gravois seems likely to cause a lot of rear-end crashes. The cyclist has a better vantage point on traffic coming up the ramp and would be better able to judge when they can safely cross the ramp. Andrew Gates, MoDOT Communication
