Last month, BoiseDev broke news of a major construction project that will impact drivers between the Boise area and greater McCall in the next few years.
Crews started work on the major revamp of about a mile of Highway 55 in ‘the canyon’ near Smiths Ferry today.
Work will take several years, and widen the roadbed south of the Rainbow Bridge, in an attempt to make the road safer. Blasting work will cut into a cliff face, and new retaining walls will go up on the Payette River side of the road. Idaho Transportation Department also plans new guardrails and other safety features.
A temporary signal will go up, allowing alternating one-way traffic. Work can happen around the clock according to the Idaho Transportation Department. Crews will also close the road down between 10am and 2pm Monday-Thursday, now through November.
Crews already had the temporary stop signal in place when our reporter went through the area Tuesday afternoon.
All work on the road will stop during the winter season, before cranking up again in March.
Work should wrap up by the late fall of 2022.
