Spring construction is wrapping up on Idaho Highway 55 between Smiths Ferry and Rainbow Bridge. Thursday, May 27th marks the last day of planned full road closures until September. Friday through Monday during the Memorial Day weekend, both lanes of the highway will be open. Then Tuesday, June 1st, our summer construction schedule begins.
This project will help improve safety and mobility for drivers by widening shoulders, minimizing roadway curves, and installing guardrail in certain locations.
“Our spring construction started in mid-March, and with full road closures Monday through Thursday from 10 a.m. to 2 p.m. crews were able to safely blast rock away from the hillside,” said Project Engineer Alex Deduck. “In two and a half months crews excavated and removed nearly 55,000 cubic yards of material, that’s more than 4,500 truckloads. We’re close to a third of the way through the project now and appreciate everyone’s patience and cooperation as we make this a safer drive.”
Crews will continue their work on the highway this summer. June 1 through Labor Day drivers should plan for one-lane alternating traffic day and night Monday through early Friday morning. Both lanes will be open on weekends Friday through Sunday to accommodate busy summer travel.
