The South Dakota Department of Transportation plans to start asphalt repair projects across the state beginning June 20.
Eight separate projects are scheduled to be completed in one to two week intervals:
- Interstate 90 eastbound and westbound – Project begins one mile west of exit 10 and ends one mile east of exit 14.
- Interstate 90 eastbound and westbound – Project begins at the Tilford Port of Entry and ends one-half mile south of exit 44.
- Interstate 90 eastbound and westbound – Project begins one and one-half mile southwest of exit 48 and ends one mile east of exit 55.
- Interstate 90 eastbound and westbound – Project begins at exit 61 extending east for one mile.
- S.D. Highway 34 – Project begins at the intersection of Regency Street and Highway 34 in Sturgis and ends at the junction of S.D. Highway 79 and Highway 34.
- Interstate 90 eastbound – Project begins at exit 110 and ends one mile east of exit 131.
- Interstate 90 eastbound and westbound – Project will conduct asphalt repairs in the exit 112 eastbound acceleration lane and the exit 112 westbound deceleration lane.

The DOT expects to work on one project at a time working from the west to east.
Interstate construction will reduce lanes and drop speeds to 45 mph during daytime hours.
Non-interstate projects will be reduced to one lane and guided through work zones with pilot cars and flaggers.
Projects are expected to be completed by Sept. 27.
