Last week, Meghan suggested some lane changes at St. Peters Parkway and Central School Road. Our traffic engineers have taken a look at the suggestion and determined not to make changes for two reasons. Primarily, the congestion at that area is short term, and would be better reduced by people using safe merging techniques (including giving people who are signaling space to move over!). However, those lane changes would require a signal rebuild; the department doesn't have any funding planned to rebuild this signal at any time in the near future. Andrew Gates, MoDOT Communications
There haven't been any signal timing changes at Lemp & Arsenal that we're aware of. I will have someone verify there isn't a malfunction occurring. Thanks for the heads up.
I will relay your concerns to the Loop Trolley contractor who is responsible for timing changes during construction of this project.
I have asked our railroad liaison to pass along your concern about graffiti to the railroad. I don't know what their policy is on removing graffiti, but if I hear anything back, I'll share it on the chat room. Andrew Gates, MoDOT Communications
A 'Road Crew' reader recently posted this question: “The signal at Reavis Road and Mackenzie Road has loops to trigger the signal to go red for Mackenzie and give Reavis a green light. One of the loops is for the right turn lane and triggers a green solely so that Reavis motorists can make a right turn. I don't have a problem with this setup per se, but I do request that the signal be modified to make the time to trigger right turns only (i.e. no through or left traffic is there) a little longer. Many times I get stopped on red at Mackenzie solely for a right turn driver. By the time the Reavis driver gets a green light, he has already cleared the intersection. So, I stopped for nobody. Thank you.”
In response, St. Louis County's Department of Transportation's signals group investigated this intersection, and shared the following information: Our inspection revealed that the intersection is operating properly and as programmed.
Installing the delay you requested would also provide a delay for the eastbound left turning movement on Reavis Road. The eastbound right turn and left turn detection loops are tied to the same signal phase and cannot be separated at the present time.
We do agree that the installation of a delay for eastbound right turning vehicles would increase the overall efficiency of this intersection. However, the installation of a delay for eastbound left turners would create longer delays for the eastbound approach and negate the potential increase in the overall efficiency of this signalized intersection. Therefore, we are unable to install the delay as you have requested.

Last week, a 'Road Crew' reader made the following request: “Westbound Big Bend, at Sappington, between 5:00 and 5:30 pm weekdays, appears to be giving too much time to vehicles turning left (WB BB > SB Sapp), which means vehicles headed east on Big Bend end up sitting through at least two cycles, because of too-limited green time, for that movement (which, I assume, should have more priority).”
Our reply: Subsequent to receiving your recent communication, we conducted an inspection of the traffic signal at the intersection of Big Bend Road and Sappington Road – Melshire Avenue. The results of our inspection revealed that the traffic signal is functioning properly and as programmed.
Our observations revealed that in the evening peak period both the eastbound through movement and the westbound left turn movement are very heavy. We made timing changes in an attempt to balance the delay for both of these movements.
We will continue to monitor this intersection to see if additional timing changes are necessary.

You are very welcome! Andrew Gates, MoDOT Communications
You are most welcome! David Wrone, St. Louis County
We are aware of it and have a project to repair it this summer. Andrew Gates, MoDOT Communications
G, are you sure you've got the right roads in mind? Unless my map and memory are both misfiring, Valcour and Heege form a "T" intersection; it's not possible to drive south on Valcour and run into Heege; Valcour starts at Gravois and runs north until it hits Heege, at which point it ceases to exist. David Wrone, St. Louis County
I'll forward this to our signals group for investigation. Thanks for sharing your information. David Wrone, St. Louis County.
We are in the process of reviewing budgets for the new fiscal year for repaving efforts, which involves the local alderpersons who routinely allocate funds to expand our ability to resurface streets in the City. I will have a better answer for you next month.
