SPEARFISH, S.D. – The South Dakota Department of Transportation says the demolition of the old I-90 Exit 14 bridge at Spearfish scheduled to start this evening, Monday, March 6, will be delayed until Tuesday, March 7, or Wednesday, March 8, when the wind subsides and it is safe for work to continue.
When work resumes, I-90 (both directions) will be closed at night (from 7 p.m. to 6 a.m.) between the off and on ramps with traffic detoured up the off ramp and back down the on ramp. Be advised that traffic will be required to stop at the top of the off ramp before proceeding down the on ramp. Each night, the contractor will clean off the interstate, secure the structure and re-open the interstate before 6 a.m.
The contractor removed the bridge deck two weeks ago and took this last week to construct supports for the removal of the bridge girders and remove debris from the bridge deck demolition. The contractor estimates the removal of the bridge girders will take six nights.
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.
