Since 1990, Ada County voters have twice approved a local vehicle registration fee to increase transportation mobility and safety. The fund, generally matched with impact fees from development, underwrite projects to reduce traffic congestion and to build neighborhood level improvements and safe routes to school under the jurisdiction of the Ada County Highway District. The current fees (shown below) expire on December 31, 2028.
