UPDATE: Perrine Bridge repairs delayed to Aug. 31
TWIN FALLS – Perrine Bridge repair and resurfacing is being delayed to Aug. 31. The project was delayed so the contractor could complete final paperwork and material submittals. The work is expected to extend the life of the iconic bridge.
When work begins, drivers may expect lane closures, and there will be impacts to pedestrian walkways. The project is expected to be complete by the end of November.

The majority of traffic-impacting activities will take place overnight between 9 p.m. and 6 a.m. The contractor may close a lane of traffic during other hours of the day to access work on the arch and underside of the bridge. One lane of traffic in each direction will remain open at all times.
Drivers can expect a reduced speed limit to 40 mph through the project.
The roadway surface work involves removing the existing seal coat and placing a new polyester concrete driving surface. The driving surface will be overlayed, and a new surface applied in October.
Concrete curbing and walls will be patched and repaired, pedestrian railing repaired, and joint seals replaced along the top of the bridge. The remaining work will take place primarily on the bridge's arch and substructure. Crews will replace broken bolts, clean debris and paint at various locations, and replace gusset and access cover plates. Overhead lighting also will be upgraded to LED lights, replacing existing sodium fixtures, which is expected to be more energy efficient.
The state-funded $2.3 million project is under contract with Cannon Builders Inc., of Blackfoot.
