Ada County Highway District
Established in 1972 as an independent government entity, the Ada County Highway District (ACHD) is responsible for all short-range planning, construction, maintenance, operations, rehabilitation and improvements to Ada County's urban streets, rural roadways (excluding state highways) and bridges.
Geographically, the Districts jurisdiction includes Boise, Eagle, Garden City, Kuna, Meridian, Star and the unincorporated areas of Ada County; it is the only consolidated countywide highway district in the State of Idaho.
The District maintains and operates approximately 2,100 miles of roads and streets in Ada County, with an estimated value of three billion dollars. This infrastructure includes facilities that range from multi-lane, arterial streets with a computerized signal system, to narrow, farm-to-market roadways.
ACHD is divided into five departments: Administration, Development & Technical Services, Maintenance, Traffic, and Plans & Development which combined, total just over 325 employees.
