SIOUX FALLS — Potsdam Avenue will be closed at Benson Road from Sept. 15 through Oct. 2 for the installation of concrete pavement surfacing. Traffic will be detoured from Benson Road to Lewis Avenue, and then back to Potsdam Avenue. Access will be maintained for local businesses.

Motorists should be prepared for delays and use alternate routes during peak travel times through the Interstate 229 and Benson Road reconstruction project. Drivers are urged to use caution and reduce their speed while traveling through the area. Traffic control measures will continue to guide motorists around all project closures.

This work is part of a $34.3 million project that will reconstruct 1.5 miles of Benson Road and portions of the nearby I-229 ramps. Work includes construction of a diverging diamond interchange, structure work, 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 project is June 27, 2025. For more information about this project, visit the SDDOT website at https://dot.sd.gov/bensonroad-i-229-pcn-04xk.
