RAPID CITY, S.D. – The South Dakota Department of Transportation says the Interstate 90 westbound exit ramp at Exit 59 (La Crosse Street) will be closed from 9:00 a.m. to noon on Thursday, March 18, 2021, to all vehicle traffic.

Westbound motorists are requested to use Exit 58 as an alternate route.

The overall completion date of this project is June 2023.
