US-12 will temporarily reopen near Arrow Bridge overnight
MYRTLE — All lanes of U.S. Highway 12 near Arrow Bridge will temporarily re-open to traffic starting at 5:30 p.m. tonight until 8:00 a.m. tomorrow morning. Crews have made significant progress on the slope above US-12 and engineers have deemed it safe to open for traffic through the night.
Drivers should expect flaggers throughout the area to monitor traffic and the slope for safety.
Work will start again tomorrow morning, closing US-12 at 8:00 a.m. If all goes as planned, ITD aims to reopen the highway at 5:00 p.m. tomorrow evening. Idaho 511 is the best resource for drivers with updated traffic conditions, detour routes and closure information.
Please use caution through the area and be aware of the possibility of debris in the roadway as work continues to clear the slope of loose rocks through the weekend.
