This project is substantially complete.

As part of the Ada County Highway District's (ACHD) Bridge Maintenance Program, ACHD will replace the culverts on Bryson Avenue and Wildwood Street, north of Fairview Avenue, as early as the beginning of November 2022 or possibly as late as mid-January 2023.* Construction is expected to be complete spring of 2023.

Both bridge improvement projects will include removing and replacing the existing bridge over the South Slough canal.

*Due to high demand for contractors, labor and supplies, the date range is designed to give the contractor flexibility so they can begin the project when resources are available.


Commuters are reminded to obey all road closure signs and follow the signs along the detour route. Commuters should never attempt to drive, bike, or walk on closed portions of the road, regardless of whether there appears to be active construction. It is unlawful to move or manipulate construction signs and doing so can put commuters and construction workers at great risk.
