Description: This line feature layer represents the collector roadway segments extracted from the Master Street Map (MSM) maintained and managed by the Ada County Highway District (ACHD) in Ada County, Idaho. Each feature corresponds to a collector street segment and include attributes such as street name, street code, street type, and typology. Collector roadways serve as the intermediate tier of the roadway hierarchy, channeling traffic between local neighborhood streets and the arterial network while also providing access to adjacent land uses. The dataset is intended to support transportation planning, traffic operations, corridor studies, capital improvement programming, and long-range infrastructure planning across the ACHD road network. Data was compiled and is maintained by the Ada County Highway District.
