Interstate 90 Lane Closures and Traffic Diversions Planned at Brandon

BRANDON, S.D. - Beginning at 7 p.m. on Wednesday Oct. 9, 2024, the South Dakota Department of Transportation (SDDOT) will temporarily close eastbound and westbound lanes on Interstate 90 and divert traffic through the on and off-ramps at Brandon (exit 406). This traffic diversion will be maintained through the overnight until 6 a.m. on Thursday, Oct. 10, 2024. This traffic pattern switch is being scheduled to remove forms from the exit bridge.

Traffic on S.D. Highway 11 will be maintained during this overnight traffic diversion. Flaggers will be posted to guide Highway 11 traffic as Interstate traffic will have priority through this traffic pattern shift. Depending on the work completed during the first night, motorists should be aware that a second night of traffic diversion is possible.

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.
