This project is substantially complete. 

As part of the Ada County Highway District’s (ACHD) Bridge Maintenance Program, ACHD will replace two separate culverts on Star Road south of McMillan Road, as early as the beginning of November 2023.* Construction is expected to be complete spring of 2024.

This bridge improvement project will include removing and replacing the two existing bridges over the Five Mile Drain and Five Mile Feeder.

*Construction schedules may change due to high demand for contractors, labor, and supplies.
