We have had several concerns shared over the past few months about an issue with the signal at Berry Road heading to eastbound I-44. I am told by our traffic engineers that they have completed the work around to correct that issue. Andrew Gates, MoDOT Communications
Also, last week Scott asked about the new I-70 ramp from Route K. I checked with our engineers and they let me know that the standard length for a entrance ramp at a location like this is just over 400 feet, before the roadway starts a 300 foot taper to merge traffic in. This particular ramp is more than 500 feet before the taper starts. So, this ramp is well over the minimum required for acceleration prior to merging into traffic. We are continuing to monitor the roadway as drivers get used to the new configuration. Andrew Gates, MoDOT Communications
Last week, a reader asked: Would someone please explain the meaning of a flashing yellow arrow on a right turn lane when the through lanes have green balls (as at eastbound Delmar turning right onto southbound Big Bend)? Online sources state that such a flashing yellow on right with green for straight ahead is meaningless and to be ignored. Is that true? ST. LOUIS COUNTY'S RESPONSE: No, that is definitely not correct. The flashing yellow arrow is designed to remind right-turning motorists to exercise caution before executing their turn. Specifically, they are intended to remind these drivers to make sure a motorist coming from the opposite direction - in this instance, westbound Delmar - isn't turning left (onto southbound Big Bend), into their path. David Wrone, St. Louis County
We expect to fully open the intersection by late August or early September. David Wrone, St. Louis County
A reader from last week's chat shared the following: The lights on northbound Laclede Station Rd/Hanley seem to be out of sync during the morning rush hour. Examples are the lights at Newport (turns red shortly after light at Big Bend turns Green), Marshall (always red when traffic arrives), Manchester (short green duration), and Hanley industrial Ct (not timed correctly). ST. LOUIS COUNTY'S REPLY: After receiving this information, our signals group investigated and found that there was in fact a malfunction in the signals on Laclede Station. This malfunction - which was creating periodic congestion on Laclede Station Road - has been corrected. Thank you for bringing this to our attention. David Wrone, St. Louis County
Thank you for your additional observations. I have shared them with the traffic team overseeing this area, so they can take a further look at the area. Andrew Gates, MoDOT Communications
Starting at 9 a.m. Thursday (July 18), the heavily traveled intersection of Laclede Station Road and Murdoch will be under flashing red control for at least four hours. A St. Louis County contractor will be removing the old signals and mast arms at this location, and activating the new signals and mast arms that will replace the old system. If possible, motorists should avoid this intersection during the switch-over, as congestion will likely be severe. David Wrone, St. Louis County
The rough sections you mention will be resurfaced next week, weather permitting. Our contractor's original schedule was upended by this week's rain. I'll forward your complaints re: Missouri American Water's water main project to the appropriate inspectors. David Wrone, St. Louis County
They are working on drainage between the new bridges and the new westbound Watson Road bridge/ramp currently being replaced. They have been working on foundation work, before the river levels got to the point where they were unable to do so in the river; they are also making some adjustments to how you get between I-270 and I-44 at the interchange (at those times when they are unable to work on the bridge in the river, due to water levels). The project is scheduled to be completed in late 2021. Andrew Gates, MoDOT Communciations
I'm sorry you missed the open house. Please email me your thoughts on the proposed project: dwrone@stlouisco.com. Thank you. David Wrone, St. Louis County
I'll forward this to our Operations group for investigation. Thanks for the heads up. David Wrone, St. Louis County
I have asked our team to reach out to Kirkwood to see if we can smooth out the timing in this area. Andrew Gates, MoDOT Communications
I checked with the County Highway Department, and they will have a patching crew come through the area to address the potholes and evaluate the condition to determine if further corrective action is necessary.
