Requests for Roadway Service, Comments, or Questions

Thank you for contacting the St. Louis County Department of Transportation to submit feedback, questions, or requests for service along County maintained roadways. We appreciate your input and will respond as quickly and efficiently as possible.

The Department of Transportation maintains the public road right-of-way of roadways within unincorporated St. Louis County and designated Arterial Roadways within many municipalities. A map of County Arterial Roadways and unincorporated areas is available at:

ST. LOUIS COUNTY ARTERIAL ROAD SYSTEM (ARS)

If your concern exists upon a roadway that is within a municipal boundary but does not lie upon a County Arterial Roadway, then that concern should be directed to the pertinent municipality.

A concern in regard to an interstate highway or a lettered or numbered State route should be directed to the Missouri Department of Transportation (MoDOT) at 314-275-1500 or at Report a Road Concern. A map of MoDOT maintained roadways within St. Louis County is available here:

Any concern about a leaking water main or other water supply facility should be directed to the Missouri American Water Company at 1-866-430-0820.
