SPEARFISH, S.D. – The South Dakota Department of Transportation says Interstate 90 at Exit 14 in Spearfish will be reduced to one lane in each direction starting the evening of Monday, Feb. 27.


This is being done so the contractor can get haul trucks and equipment in and out as they remove the debris from the demolition of the bridge deck at the Exit 14 construction project. This work will be done only during daylight hours. In concurrence with removing debris the contractor will also be erecting scaffolding to support the girders during the removal process.


The lane closures will change throughout the week as the work progresses from the median to the outside shoulders and motorists will need to pay attention to signing.


Work to remove the girders (with overnight closures of I-90) is scheduled to resume the week of March 6, 2017.


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.
