Bridge Construction On I-90 Means Overnight Lane Closures

An ongoing construction project on Interstate 90 in South Dakota is about to enter a phase.

Timeline

According to the South Dakota Department of Transportation, starting June 25 at 7:00 PM, the eastbound and westbound lanes on I-90 at the Brandon exit (Exit 406) will be temporarily closed for crews to set bridge girders. During the closure, traffic will be diverted through the on-ramps and off-ramps and back onto I-90. This traffic diversion is scheduled to remain in place until 7:00 AM on June 26.

The same lane closures and traffic diversions are also planned from 7:00 PM June 26 to 7:00 AM June 27. The second night of the scheduled traffic diversion is for crews to install components to build the bridge deck.
