Heads Up Drivers, I-90 Onramp Closure Is Just Around The Corner
Drivers West of Sioux Falls will have one fewer way to access the interstate later this week
According to the South Dakota Department of Transportation, beginning at 6:00 AM on Thursday (September 11), the westbound Interstate 90 on-ramp at Hartford (exit 387) will be temporarily closed. The temporary on-ramp closure is required to allow crews to safely complete a bridge deck pour over I-90.
Concrete trucks will need direct access in and out of the work zone during this bridge deck pour operation. The on-ramp will be reopened as soon as the deck pour is complete. The on-ramp is anticipated to reopen by 12:00 PM.

During the temporary on-ramp closure, traffic will be routed to the I-90 eastbound on-ramp exit at 387 and travel three miles east. Motorists can then use the westbound on-ramp at exit 390 to travel westbound on I-90. Drivers are encouraged to allow for extra travel time and use alternate routes if possible.
The $12.6 million project is expected to be completed by June 2026.
