Thank you -- I've shared your additional thoughts with the traffic team that oversees that area. Andrew Gates, MoDOT Communications
We maintain this signal. I'll forward your report to our Division of Operations for investigation. Thanks for the info. David Wrone, St. Louis County's Department of Transportation

MoDOT maintains interstates and stated numbered and lettered routes - like Route D or Route 340, with a very few exceptions. Any roadways that have an interstate shield, a U.S. Route shield or a sign with the outline of the state of Missouri with a number or letter in it, MoDOT maintains. Within the city of St. Louis, the city is responsible for all the other roadways. Stepping in Dave Wrone's territory a bit, you can use their arterial road system list: https://stlouiscountymo.gov/st-louis-county-departments/transportation-and-public-works/roadway-publications-and-manuals/dot-other-publications-current/arterial-road-system-ars/. Otherwise, it's municipality maintained. However, you can always contact one of us, for instance, MoDOT's 24/7 customer service line is 314-275-1500 and ask. Most of the time we can steer you in the right direction. Andrew Gates, MoDOT Communications
Re: road/street maintenance responsibility, we also maintain those residential streets located in unincorporated areas of St. Louis County. But, as Mr. Gates noted, munis are responsible for residential streets located within their borders. David Wrone, St. Louis County's Department of Transportation
Gravois between 141 and i-270 is Missouri Route 30, just like the rest of Gravois into the city. Manchester, west of Westglen Farms, is Missouri Route 100, just like the rest of Manchester Road into the city (except for the portion within the city limits that is Chouteau). Andrew Gates, MoDOT Communications
I have asked our maintenance team to have a look at this area -- it may be the start of a developing pavement issue. Andrew Gates, MoDOT Communications
You are correct in those specifics. There are some sections of old roadway that were turned over to municipalities (or used as outer roads) when the roadway was rebuilt or relocated. MoDOT doesn't maintain the section of Manchester you speak of (where it spurs off Route 100) and some -- though not all -- of that Gravois road section acts as an outer road for Route 30. The section between I-270 and Route 141 is pretty far away from Route 30, and so isn't maintained by the department. Typically outer road sections don't get their own letter/number. Andrew Gates, MoDOT Communications
I'll ask our traffic team to take a look at this, but typically, it is the responsibility for the developer to install all the necessary signs. Andrew Gates, MoDOT Communications.
Thanks for the reports. I've forwarded them to our Operations team. I'll answer your question re: Big Bend and Rock Hill Road in next week's chat. David Wrone, St. Louis County's Department of Transportation
To continue my observations from last week, about NB I-270, if/when the signs do get replaced, the two for I-64, south of Clayton Road, would be less confusing if they weren't split into two halves (for east/west & north/south) and just displayed the 3 highway numbers, over the one exit-only lane. The one north of Clayton Road, over the two exit lanes, would then make more sense, in it's present configuration, with two halves. Thanks!
