All St. Louis County offices are open to the public. Currently, the COVID-19 Community Level is high in St. Louis County, which means facemasks are recommended inside St. Louis County buildings (and all indoor public places.)



Help Keep the Roads Clean

St. Louis County's Adopt-A-Highway program is a public service opportunity for companies, clubs, churches, families and other organizations interested in keeping a county road segment clean. Participants are provided safety vests and garbage bags. St. Louis County will also install Adopt-A-Highway signs on your county road segment to recognize your organization’s service.

To begin, an organization must select a group administrator. This person is responsible for applying for the Adopt-A-Highway program and then serves as the point of contact for communication from St. Louis County. Once approved, a group must complete at least two (2) clean-ups every 12 months. Typically the clean-ups are completed in the spring and fall.

To apply for a segment, or to view an existing account, use the links below to launch the St. Louis County Adopt-A-Highway Mapping Application.

Please Note: The Adopt-A-Highway Mapping Application is currently not optimized for viewing on a mobile device. We recommend viewing the application on a desktop computer or laptop. Production is underway for creating a mobile-friendly version of the application.
