SHOSHONE, Idaho (PRESS RELEASE) – A 10-mile-long paving project paired with two culvert replacements and bridge rehabilitation work begins Monday (July 18) along Idaho 75 in southern Blaine County. The pavement-preservation project will extend the life of the existing roadway and the Richfield Canal bridge.

The initial phase of the project will replace a stormwater culvert and rebuild the roadway at another culvert — both located near milepost 100 about two miles south of the U.S. 20 intersection (Timmerman Junction). At both existing culvert crossings, the roadway foundation has settled, resulting in cracking and a dip. Repairs and rehabilitation will also take place on the bridge over the Richfield Canal and the driving surface.

During the first phase of the project, traffic will be reduced to one lane at each location with temporary traffic signals controlling the flow of traffic through the work zones. Drivers can expect minor delays up to five minutes long at each location.

Following bridge and culvert work, an asphalt overlay will be placed over the entire stretch of Idaho 75 between the Richfield Canal and the U.S. 20 intersection. The project will improve roadway smoothness and protect against additional roadway cracking.

Traffic will be reduced to a single lane through the active work area of the construction zone. Drivers should watch for flaggers and expect delays of up to 15 minutes. A pilot car will be in operation and a 15-foot width limit will be in effect.

All paving should be completed by the end of August. A seal coat will be applied to the roadway in 2017.

The $1.75 million project is under contract with Idaho Materials and Construction, of Twin Falls.
