BRANDON, S.D. – Beginning at 7 p.m. on Wednesday, June 25, 2025, the eastbound and westbound lanes on Interstate 90 at exit 406 (Brandon) will be temporarily closed for crews to set bridge girders. During the closure, traffic will be diverted through the on- and off-ramps and back onto I-90. This traffic diversion is scheduled to be in place until 7 a.m. on Thursday, June 26, 2025.

Lane closures and traffic diversions on I-90 at exit 406 (Brandon) are also planned from 7 p.m. on Thursday, June 26, 2025, through 7 a.m. on Friday, June 27, 2025. The second night of the scheduled traffic diversion is for crews to install components to build the bridge deck.

Traffic on S.D. Highway 11 will be maintained during both overnight traffic diversions and guided through the work zone with the use of flaggers.

The second phase of reconstruction on this DDI project includes completing the remaining on- and off-ramps, the eastbound lanes of I-90, the Exit Bridge, and the replacement of the eastbound I-90 bridge over the BNSF railroad. Weather dependent, the second phase of construction will be ongoing until November 2025.

The prime contractor for this $41.3 million project is T & R Contracting of Sioux Falls, SD. The overall completion of the DDI reconstruction project at Brandon (exit 406) is June 2026.
