 "serviceDescription": "<div style='text-align:Left;'><div><div><div style='font-size:12pt'><p><span> This line feature layer represents the arterial 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 an arterial street segment and include attributes such as street name, street type, exist lane, parking, typology, ROW project and street code. Arterial roadways serve as the primary corridors for moving higher volumes of traffic across the county, connecting major destinations, activity centers, and collector routes. The dataset is intended to support transportation planning, corridor studies, traffic operations, 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.<\/span><\/p><\/div><\/div><\/div><\/div>",
