For Immediate Release:  Monday, January 9, 2017

Contact: Adam McMahon, 605-892-2872


SPEARFISH, S.D. – The South Dakota Department of Transportation says that eastbound I-90 will be reduced to one-lane between the off and on ramps at Exit 14 on Tuesday, Jan. 10, 2017. This is being done so the contractor can transport concrete barriers onto the new bridge.


Then, on Wednesday, Jan. 11, traffic on 27th Street will be switched onto the east half of the new bridge.


Once traffic is switched onto the new bridge the contractor will be able to start work on the demolition of the old bridge.


Motorists are asked to slow down through the work zone and be prepared for suddenly slowing, merging and stopped traffic, as well as construction workers and equipment 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.
