On Friday the Idaho Transportation Department will shift traffic from existing State Highway 54 to the new section of pavement between SH-41 and Ramsey Road.
Drivers will be routed onto this new section of roadway while crews begin rebuilding the existing lanes. During this time, the speed limit will be reduced to 45 mph and passing will not be allowed for the remainder of the construction season.
In the coming days and weeks, access to side streets and driveways in the area will be temporarily closed as crews work directly in front of them, but closures will be short and only in place as long as necessary – likely an hour or less. Drivers should pay attention to local signage for closures and detour routes as work rolls through the area.
This traffic shift marks a key milestone in the ongoing highway improvement project which is on track to be completed in 2026.
Drivers are urged to use caution in the area and watch for flaggers and signs.
Idaho 511 is available as a resource to provide updates on construction impacts and road conditions state-wide.
