PIEDMONT, S.D. – The South Dakota Department of Transportation says the reconstruction project on Interstate 90 near Piedmont has entered Phase 3.

 

On Thursday, Aug. 17, the westbound lanes of Interstate 90 were closed from about two miles west of Exit 44 through the Exit 40 interchange.

 

Westbound traffic has been routed to two-way traffic in the eastbound lanes of I-90 Westbound Exit 40 is closed with a detour route provided via Exit 44 and the Spring Valley Road service road.

 

The closures are expected to remain in place through late November when the interstate will be reopened for the winter.

 

Work during this phase is for the reconstruction of the westbound lanes of I-90 and includes grading, concrete surfacing and the construction of a new bridge over Elk Creek.

 

Phased 1 and 2 are complete and included box culvert extensions along the westbound lanes; reconstruction of two miles of interstate westbound lanes near Exit 44; and the construction of new bridges at Exit 44 and Little Elk Creek.

 

Phases 4 and 5 will reconstruct the eastbound lanes of I-90 between Exits 40 and 44. As part of the project, grading for three lanes in each direction will also be done, however, only two lanes will be paved in each direction at this time. There is no current time table for paving of the third lanes.

 

Motorists are asked to be prepared for suddenly slowing traffic and merging traffic, as well as construction workers and equipment adjacent to the roadway.

 

Heavy Constructors, Inc. of Rapid City is the prime contractor on this $29 million project.

 

The overall completion date for the project is June 14, 2019.
