Traffic switch scheduled on S.D. Highway 11 at I-90 near Brandon

On Friday, Aug. 30, a traffic switch is scheduled on S.D. Highway 11 south of the bridge at Interstate 90 (exit 406) at Brandon. Traffic that is currently placed in the northbound lane of Highway 11 will be switched to the southbound lane to allow work to begin south of the bridge.

Motorists on Highway 11 will be switched to the two southbound lanes beginning at Redwood Boulevard to the south end of the bridge. Access to businesses on the east side of Highway 11 will be maintained during operations through direct access or by detour routes. This traffic diversion will be in place for approximately three weeks until grading and paving work in the northbound lane of Highway 11 is completed.

This project includes the reconstruction of exit 406 at Brandon with added lighting, signals, and mainline Interstate work. This project also includes three structure replacements. The interchange will be reconstructed as a Diverging Diamond Interchange (DDI). Westbound I-90 lanes (along with the railroad structure on I-90) will be reconstructed in 2024 and the eastbound lanes in 2025. The interchange itself and new structure over I-90 will be reconstructed between the 2024 and 2025 construction seasons.
