RAPID CITY, S.D. – The South Dakota Department of Transportation says rehabilitation work on the Haines Avenue and Maple Street bridges on Interstate 90 in Rapid City is set to begin Monday, April 16, and will impact traffic during much of 2018.
Construction is scheduled to begin Monday, April 16, 2018, in the eastbound lanes of I-90 with construction on westbound I-90 set to begin Aug. 13.
During Phase 1, the eastbound lanes of I-90 will be reduced to one lane through the work zone and both the I-190 northbound to I-90 eastbound on-ramp and the Exit 58 (Haines Avenue) eastbound on-ramp will be closed. Detours will be in place for all ramp closures.
Work is scheduled to be completed in the eastbound lanes of I-90 by late July, before the start of the Sturgis Motorcycle Rally.
Work on the bridges in the westbound lanes of I-90 is scheduled to be completed between Aug. 13 and Nov. 16. During this phase, westbound I-90 will be reduced to one lane through the construction zone and the Exit 59 (Lacrosse St.) westbound on-ramp will be closed with a signed detour.
Rehabilitation work involves removing and replacing the bridge approach slabs and approach pavement, repairing unsound concrete on the bridge decks, placing a high friction surface treatment on the Haines Avenue bridge and a new concrete overlay on the Maple Street bridge, along with barrier curb modifications.
Heavy Constructors, Inc. of Rapid City is the prime contractor on this $2.3 million project.
