Good morning. A few follow ups from last week. Billy-boy was asking about the bike symbols along Jefferson through the new interchange. I did speak to the construction team, and they let me know that they still need to paint the shared bike lane symbol through the interchange. They let me know that they hope to have that done once the weather breaks enough to do so.Michael was asking about whether we have analyzed the impacts of not using flashing yellow arrows overnight. I heard back from our traffic team and we did do a study shortly after we implemented the policy. Our traffic team let me know that our findings were very similar to those in the FHWA study.Christ2fer asked about signal timing at the ramps at Dougherty Ferry and I-270. We have a team looking at the signal timing along the I-270 corridor and we have passed your observations along to them to consider as they work on improving traffic flow onto the interstate.We also had a question, that I don't believe was posted, about the Riverview closure. Although MoDOT is responsible for maintaining the surface, signals and striping along the Route H corridor, the city oversees items like permitting. In this case, this is an MSD permit that is set to run a couple more weeks, according to what we were able to determine.Andrew Gates, MoDOT Communications -

You can see the projected overall plans for the project here: I-270 North Project (i270north.org). Yes, Dunn and Pershall will be one-way. The project will continue through 2023. Andrew Gates, MoDOT Communications

Again about tge I-270 project. What is the reason for making Dunn and Pershall one-way? It seems likely that this will hurt many businesses along those roads. And I don’t remember there being a large number of accidents caused by the two-way traffic that we’ve always had. Thank you.

The slip ramps onto and off the interstate created a fairly significant safety concern. Dunn Road will travel westbound as a one-way road starting east of the Old Halls Ferry interchange and ending at Hanley/Graham. Pershall will travel eastbound as a one-way road beginning at the Hanley/Graham interchange and ending at Old Halls Ferry. The one-way conversion creates an updated outer road system that allows for removal of all cross over slip ramps. The result will be improved safety and improved traffic flow throughout the corridor.

A question for MoDOT. I saw a brochure from MoDOT detailing its responsibilities on state roads in St. Louis County maintained by MoDOT. In the same brochure it liad out the responsibilities for state roads in St. Louis City and there were significant differences, probably stemming from the fact that MoDOT didn't acquire these state roads from the city in the 1950s as occurred with most cities and counties.
I'm guessing that MoDOT doesn't own adjoining sidewalks, street lights, control parking, among the list. Am I on track with my speculation? -
As a part of the agreement for the state numbered and lettered routes in the city, the department maintains curb to curb -- that includes signing, striping, maintaining the driving surface, sweeping and signals. There are a few roadways in the city that MoDOT maintains the driving surface only. Generally speaking, the city retains the remainder of the responsibilities. Andrew Gates, MoDOT Communications

Dave,
I am inquiring about some sidewalk work on the south side of Concord Village Ave by a plaza that houses P'sghetti's Pasta and Sandwiches. There is a circular mound of asphalt, it almost looks like it could be a planter, but it's not. It appears to be a crude attempt to make a traffic island that makes drivers on Concord Village turn left stay to the left. I can't tell if the circle is on county right-of-way or on the parking lot.
Anyway, it makes no sense to run new sidewalk and have it terminate at this circular mound of asphalt. Is the ring of asphalt scheduled to be removed? Please advise. Thank you. -

I moved to the City of St. Louis a few months ago and have discovered a terrible truth: So many traffic signals are on old-fashioned, antiquated timers.
Here’s an example: Tower Grove Ave & S Vandeventer Ave. This is one of those “5-way” intersections because there’s also a side road called “Central Industrial Dr” that no one drives down.
So why does Central Industrial Dr get a 30 second green signal at all hours of the day and night? It shuts down the entire intersection. I have never seen anyone drive down that road.
What needs to happen to get someone out to that traffic signal controller box to adjust the timing? Or can I just walk up to it, open it up and fix it myself? Thanks. -
The intersection of 141 and Page, specifically the stoplight on the south side of Page. 141 SB has a stoplight that is no longer needed as the left turn to 141 from EB page has been moved to the stoplight north of Page. There is no longer a need to stop the cars there anymore unless I am missing something.

In Crestwood, on Big Bend, given that the stacking lanes for turning left onto both I-44 and into Sam's Club, are short, busy and "over-subscribed", has any thought been given to moving the stop bar further west, to accommodate one more vehicle? Since it's a T intersection with no crosswalk, I don't see a need for it to be setback as far as it is, currently.

Again, last week, I witnessed a semi driver confused by the signage for I-64 on NB I-270. He/she forced their way into the exit lane, at/beyond the gore point, because exiting traffic was pretty solid/already in that lane, from about Clayton Road. This was about 10 am on a Tuesday.
-
There are several signs along I-270 indicating the upcoming interchange and even sharing information about how traffic flows as you approach the I-64 interchange. I will, however, share your observation with our traffic team to see if they can do anything additional. Andrew Gates, MoDOT Communications

The light at the bottom of the WB Manchester Road to Des Peres Road ramp is set to favor Des Peres Road. It takes a VERY long time to change for the ramp traffic, even when Des Peres Road traffic is non-existent. Can the timing be looked at for this? It happens at all times of the day, even though I mostly experience it between 6:30 and 8:30am. Thanks.

The problem is that the two signs south of the Clayton overpass visually split WB & EB I-64 on the green part of the sign but share a single, common arrow for the Exit Only yellow portion. It's only after the Clayton overpass that there is the one sign with two "Exit Only" arrows. While all three signs are technically "correct", over the exit lane/lanes, many drivers interpret the Exit Only as applying to only EB I-64 traffic (given there's only one shared exit lane south of Clayton), assuming that a different lane will become available for WB I-64 traffic. This is mostly because the two southern signs are split into two halves, vertically, instead of just saying I-64 as one large sign, for both directions.

To piggyback onto Eric's question, there is also the same situation at Eichelberger and Christy. There is a five-way intersection with Hummel Ave.
Also, the signal controller at Jamieson and Lansdowne avenues was replaced a few years ago. The old electro-mechanical box was upgraded with a new cabinet. Is there detection for this signal? If there is, it appears not to be working. If there isn't detection, please add it. It's a frustrating signal, waiting for a green light on Jamieson once traffic clears Lansdowne and also, the opposing green arrow on Jamieson always comes on whether a car is in the left-turn
lane, or not. -

Yes -- the signals over those two lanes are only green arrows. That is to make sure that through drivers on southbound 141 don't mistake the stop signal (for the left turn lane) as being for them (and stop unnecessarily.) Andrew Gates, MoDOT Communications
