PIEDMONT, S.D. – The South Dakota Department of Transportation says the westbound lanes of Interstate 90 from Exit 44 at Piedmont, going west, will be closed for about two miles beginning March 6.


Westbound traffic will be routed to the eastbound lanes of I-90 where traffic will be in a two-way configuration. In addition, beyond the two-way traffic configuration, the westbound driving lane is anticipated to be closed all the way to Exit 40.


The closures are anticipated to remain in place through late July when the interstate will be reopened for the Sturgis Motorcycle Rally.


The closure is necessary for the reconstruction of the westbound lanes of I-90. Work will include grading, concrete surfacing and the construction of new bridges. The westbound portion of the Exit 44 interchange will also be reconstructed with longer on and off ramps.


This is Phase 2 of a five phase reconstruction plan. Phase 1 was done earlier and included box culvert extensions along the westbound lanes; Phase 3 will reconstruct the remaining portion of the westbound lanes to Exit 40 and will begin after the Sturgis Motorcycle Rally in August.


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 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.
