There are a number of streets within the City of St. Louis that are maintained by the Missouri Department of Transportation (MODOT). The easy way to figure out which streets are to look at the official name. If it has a number or letter in it such as MO 100 or Route D, it is maintained by MODOT.
What exactly does maintained by MODOT mean though? MODOT is in charge of all amenities curb-to-curb including the driving surface, road striping, and signals. The City of St. Louis is in charge of lighting, parking meters, sidewalks, and access rights on all roads.
If you encounter a problem on a state-owned road regarding a curb-to-curb amenity, call (314) 275-1500 or 888-ASK-MODOT. Their call center is open 24 hours 7 days a week. If your maintenance request is the responsibility of the city, call (314) 622-4800 Monday – Friday, 8am – 5pm or by submitting a request through the Citizens’ Service Bureau.
