SIOUX FALLS, S.D. – Starting Monday, April 1, 2024, the South Dakota Department of Transportation (SDDOT) will begin reconstruction work on Benson Road and the Interstate 229 interchange.  

Benson Road will remain open to traffic as the contractor works on the south driving lanes of Benson Road from Casco Avenue to I-229. Traffic will be maintained on the north side of Benson Road. Access will be maintained to businesses throughout the project.

The project will reconstruct nearly two miles of Benson Road and approximately one mile of Interstate 229 ramps. Work includes construction of a Diverging Diamond Interchange (DDI), constructing a structure, grading, concrete surfacing, curb and gutter, storm sewer, lighting, signals, permanent signing, and pavement marking.

The prime contractor for this project is T&R Contracting of Sioux Falls. The overall completion date for this $34 million project is June 2025.
