Public comments sought on South Dakota Highway 44, Platte-Winner Bridge Draft Environmental Assessment

Published June 2, 2023

The South Dakota Department of Transportation, Federal Highway Administration and the U.S. Army Corps of Engineers, Omaha District are seeking public comment on a draft environmental assessment (EA) to evaluate the impacts of the proposed Platte-Winner Bridge replacement project located in Gregory and Charles Mix Counties on South Dakota Highway 44.

The study is being held to address the deteriorating conditions of the Platte-Winner Bridge and review the SD44 corridor and identify any safety issues. The purpose of the proposed project is to construct a new two-lane bridge carrying Highway 44 over Lake Francis Case on the Missouri River to replace the aging existing Platte-Winner Bridge.

The current alignment of SD44 over the river has experienced numerous landslides, resulting in millions of dollars in repair and mitigation efforts since the bridge opened in 1966. The proposed project will include an emphasis on minimizing environmental and socioeconomic impacts.

The SDDOT has prepared a draft EA in cooperation with the Federal Highway Administration, the U.S. Coast Guard, and USACE.

The public is encouraged to provide comments on the draft EA which can be viewed and downloaded at: https://sd44bridge.com/documents/.

Comments should  be submitted electronically by Friday, July 7, 2023, at: https://sd44bridge.com/comments/.
