SPEARFISH, S.D. – The South Dakota Department of Transportation says lane closures will be set up on I-90 starting on Monday, April 2, at Exit 14 in Spearfish to complete work on the project. 


Crews will be working on the following items during the next couple of months: concrete median pavement, curb and gutter, sidewalk, retaining wall, traffic signals, permanent signing, interstate median paving, cable rail, bridge end expansion joints, seeding and permanent pavement markings.


Crews will also tackle corrective items like bump grinding and replacing concrete panels that have cracked.  


Motorists are asked to slow down through the work zone, be on the lookout for flaggers, suddenly slowing, merging and stopped traffic, and construction workers and equipment entering, exiting and adjacent to the roadway.
