Ever wonder how the Ada County Highway District came to be? Potholes! Fed up with bad roads they spent too much to maintain, voters overwhelmingly approved a new agency to oversee all of Ada County’s local roads.

ACHD believes this will help build safer, smarter and more efficient roadways. The Ada County Highway District's Traffic Division is responsible for planning, designing and managing efficient traffic flow and traffic safety throughout Ada County.

The Ada County Highway District (ACHD) is the only countywide highway district in Idaho. Located in Garden City, Idaho , it is a government agency established in 1971 as an independent government entity.
