South Dakota: Section of US Highway 385 will be closed

As part of the state's US Highway 385 reconstruction project, two full closures are planned on the only north-south highway through the Black Hills of South Dakota.

The first closure, which began on May 20, affects the road between the Pactola North boat ramp and the Pactola Dam. It will remain completely closed to traffic for eight weeks and will reopen on July 12.

U.S. Highway 385 between State Highway 44 and the road to the Pactola North boat ramp will also be closed to all traffic, with temporary openings on weekends. Reopening is scheduled for June 7.

“The complete closure was deemed necessary for the safety of road users and the efficiency of the project due to the large amounts of material being blasting and moved in the closed areas,” the South Dakota Department of Transportation said.

During the closure in South Dakota, wider shoulders will be built on both sides of the road, improved road curves to current design standards, additional turning lanes to improve traffic flow, and a new road surface will be built.

The posted detour runs via State Highway 44 and US Highway 16. SDDOT recommends travelers use caution when driving on unmaintained roads.

South Dakota officials said emergency services were working closely together to provide the necessary emergency coverage.

Some boat ramps on Pactola Lake will also be temporarily inaccessible during the closure of U.S. Highway 385 in Pennington and Lawrence Counties.

The project also includes future construction phases near Sheridan Lake in 2025 and 2026. Surface completion is scheduled for 2027, according to the project website.
