Idaho 75 Paving, Temporary Access Closures Begin Friday


By Paul Johnson

Ketchum, Idaho – Reconstruction of a 3.25-mile section of Idaho 75 is in its final stages, with the last major hurdle beginning this week. Paving the northbound lanes between East Fork Road and the Big Wood River Bridge is expected to begin Friday August 15,resulting in temporary closures of access points over the next two weeks, the Idaho Transportation Department announced.

Paving will begin at the south end of the project and proceed north. Work will consist of paving one of the two lanes the first day, followed by the second lane. Without delays, the contractor expects to be complete with the bottom layer in four days. The second layer will follow a similar pattern, and also is expected to take four days. Crews will then pave all intersecting roadways and access approaches throughout the project.

The contractor will mill out portions of temporary asphalt from work completed in 2013 and repave small sections.

Access points will temporarily close as paving moves north. There is insufficient room for temporary access to roadways and approaches. The temporary closures are not expected to exceed 30 minutes, but could have longer impacts when crews work on the top layer of asphalt.

Drivers are asked to watch for lane changes and traffic impacts throughout paving, and to watch for flaggers and construction trucks entering and exiting the work zone.
The contractor also will grade shoulders, construct fence, install rodway signs and guardrail, and stripe the roadway in the coming weeks.

When completed, Idaho 75 will be widened to two lanes in each direction with intermittent center turn lane and turn bays for access into residences and businesses.
Throughout construction, one lane of traffic will be maintained in each direction but traffic may be stopped or delayed as needed.
