April 12, 2024 - Construction Detour Map

Next week, the closure on State Street will be extended behind the Capitol Building.

The road is currently closed between 4th and 6th Streets. Beginning Tuesday, State Street will be closed between 4th and 8th Streets. This closure will include the intersections at 4th, 5th, 6th, and 8th Streets.

Commuters should use Washington Street or Jefferson Street as a detour (see updated detour map).

The intersection at 8th Street is expected to reopen this summer. Work on the rest of the project is expected to last until the end of November, weather dependent.

The work is part of ACHD's State Street, 8th Street to 4th Street project, which includes reconstructing the roadway, upgrading traffic signals, and upgrading the enhanced crosswalk behind the Idaho State Capitol to an overhead rectangular rapid flashing beacon (RRFB).
