Established in 1972 as an independent government entity, the Ada County Highway District (ACHD) is responsible for all short- and long-range planning, construction, maintenance, operation, rehabilitation and improvements to Ada County's urban streets, rural roadways (excluding state highways), bridges, and Stormwater monitoring. Geographically, the District’s jurisdiction includes Boise, Eagle, Garden City, Kuna, Meridian, Star, and the unincorporated areas of Ada County. It is the largest highway district and the only consolidated countywide highway district in the State of Idaho and the nation. ACHD maintains and operates over 2,300 miles of roads and streets in Ada County with an estimated value of $3 billion. Elements of ACHD's infrastructure include multi-lane arterials, collector and local roadways, farm-to-market roadways, sidewalks and bike lanes, and bikeways, along with a state-of-the-art computerized signal system to improve traffic flow. The District also purchases rights-of-way necessary for future infrastructure improvements.
