SPEARFISH, S.D. – The South Dakota Department of Transportation says eastbound I-90 will be closed from 4 a.m. to 6 a.m. on the morning of Tuesday May 16, with traffic directed to the off and on ramps.


The closure is taking place so equipment can be moved into the median to begin construction on the west half of the center bent of the new bridge.


Interstate traffic will be routed up the off ramp and back down the on ramp. The contractor will clean off and re-open the interstate before 6 a.m.


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


Heavy Constructors, Inc., of Rapid City is the prime contractor on this $28 million project. The overall completion date for the project is June 1, 2018.


Road construction information for this project can be found at the following locations as it becomes available:
