US-93 widening begins north of Twin Falls

US-93, 300 South Road

Work will begin today to widen one mile of U.S. Highway 93 north of Twin Falls. Drivers should expect minor delays while crews start moving utilities and working on the shoulders. Major work and impacts won’t start until early January.

Construction will expand US-93 to four lanes between 200 South Road and 400 South Road. Other changes include reconstructing the railroad crossing, widening highway shoulders and building left and right turn lanes at 300 South Road and other business developments.

Once utilities are relocated, canal reconstruction will start and take through early March and be followed by roadway work in the spring.  Two lanes of traffic will be maintained throughout construction with minor detours of intersecting roads later in the project. New lanes are expected to be open to traffic in October.

This will be the fourth and final segment of the overall corridor, between Twin Falls and Jerome, to be widened, with previous widening projects completed every year since 2018.
