SHERIDAN LAKE, S.D. (AP) — A project to widen and straighten a 15-mile section of the only north-south highway through the central Black Hills is fully underway.
U.S. Highway 385 is a busy work zone with a rocky roadway, construction equipment grinding on the hillside and a flagger stopping all traffic.
During three planned closures this year, drivers will be required to follow a roughly 50-mile detour. The $72 million project’s main goal is to improve safety on the highway, which in spots has narrow or no shoulder and is flanked in spots by deep canyons or tall pine trees.
Construction will include widening road shoulders, smoothing out sharp curves and adding turn lanes.
