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.Five Commissioners govern the District. Together, they are responsible for guiding the planning, development and implementation of transportation facilities throughout the county. Elections are held every two years on a rotating basis, and each Commissioner represents a separate subdistrict.Because strong public involvement is crucial to the transportation planning process, the Commissioners and staff regularly host and attend meetings and public hearings to gather feedback from concerned citizens. The Commissioners also hold regular public meetings at the Districts headquarters, and participate in joint meetings with municipal and county officials.An appointed Director, who serves as chief administrator, manages the District on a day-to-day basis. The Director is responsible for managing five departments: Administration, Engineering, Maintenance and Operations, Traffic, and Plans & Development which combined, total nearly 300 employees.
