BRANDON, S.D. - On Tuesday July 16, 2024, the South Dakota Department of Transportation (SDDOT) will begin a temporary signal for one-way traffic across the Exit Bridge on S.D. Highway 11 over Interstate 90 at Brandon. Traffic at the bridge ends will be signaled to one lane. This one-way traffic diversion will be maintained until Friday, July 19, 2024.

This project includes the reconstruction of exit 406 (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.
