Traffic Disruptions Ahead As I-90 Construction Ramps Up

Even though summer is winding down, there is still no end in sight for the ongoing road construction projects impacting drivers on the interstates around the Sioux Falls area.

The latest lane closures are coming to Interstate 90.

When and Where

According to the South Dakota Department of Transportation, beginning at 8:00 PM Monday (August 4), the eastbound lanes of Interstate 90 in Hartford (Exit 387) will be temporarily closed to allow crews to set bridge girders.

During the closure, eastbound I-90 traffic will be diverted to the Exit 387 on-and off-ramps, then back onto I-90.

Those lane closures will be in effect until 6:00 AM Tuesday (August 5).

The westbound on-ramp at Exit 387 will also be closed from 8 p.m. to 6 a.m. Drivers needing westbound access should use Exit 390 as an alternate route.

End Date

The same traffic diversion and westbound on-ramp closure will occur again from 8:00 PM Tuesday through 6:00 AM Wednesday.

Western Avenue (County Highway 151) will remain open during both overnight operations. Traffic will be guided by flaggers through the work zone.
