We have a contractor working to fully replace the signal, so it may be a part of that. We will check into it and see what we can do to get it active again. Andrew Gates, MoDOT Communications
Crews are currently working on updating signals on Gravois at Mackenzie and Weber. Once the new signals are in later this year, our traffic engineers will tweak timing for them., which may include coordination, if appropriate. Andrew Gates, MoDOT Communications

Corridors, such at Watson Road, are optimized for traffic flow. During period of heavy traffic (for instance morning or evening rush) signals give more time to the direction that typically has the most traffic (where the rush traffic is going) . The goal is, as much as possible, to have a driver who is traveling through the corridor in the direction of rush traffic, at the posted speed limit, stop as little as possible. That often means that the other direction will have to stop more (as there is limited amount of time that traffic crossing the corridor has to do so). That is why, when people have specific concerns about signal timing, we ask for direction and time (that can help us determine if if is issue where the traffic flow is optimized for the opposite direction). As you can imagine, this requires a lot of calculations and is often a work is progress as traffic patterns change. We do have engineers monitoring our signals and they can make changes on the fly if there is a crash or other incident which is pushing more traffic than usual onto a corridor. Outside of rush periods, when traffic levels are lower, the signals will often use detection to determine if there is traffic in a certain direction and change to move that traffic through. Andrew Gates, MoDOT Communications
At most, signals along an optimized corridor are coordinated (i.e. they are tied together to work together), but they are not going to change in a sequential pattern as you describe -- although the optimization would try to maximize that as much as possible. However, synchronization as you describe might interfere with the optimization on the intersecting corridor. However, if you see something that seems to stand out, I can certainly share it with our traffic team -- we can often make tweaks to help improve flow. Andrew Gates, MoDOT Communications
MoDOT funding comes primarily from gas tax, drivers license fees and vehicle licensing fees, not directly from state sales tax or personal property tax. Although not collecting licensing fees would impact the funds available for the roadways, changing how that is collected would be the purview of the Department of Revenue, and may even have to come through legislative action. You are correct, though, enforcing license plate issues is the responsibility of law enforcement. Andrew Gates, MoDOT Communications
That ramp resurfacing doesn't get done with the Jefferson job, but with a future job on I-55. I have passed the pothole concerns on to our maintenance forces to work on. Andrew Gates, MoDOT Communications
I've asked our traffic team to check that out. Andrew Gates, MoDOT Communications
That was a permit project done by Ameren Missouri to relocate poles. It was supposed to be complete by the end of April. You might have to check with them for more specifics on what, exactly, they did. Andrew Gates, MoDOT Communications
We are waiting for some of the asphalt they just put down to cure before putting down final striping. They hope to do that the week of May 16, so it should be complete, weather permitting, by late May. Andrew Gates, MoDOT Communications
