Description: | An article in the August 2012 issue of Roads & Bridges titled, "Design Innovation: Quick Replacement" describes how the Nevada Department of Transportation (NDOT) used accelerated bridge construction (ABC) to move a bridge 60 feet across I-15 at the West Mesquite Interchange in approximately six hours without closing the road. Traffic was routed up and down the ramps at the Interchange to maintain some traffic flow. The use of ABC allowed NDOT to build the bridge for more than $10 million less and six months faster (reducing traffic disruptions from months to days) than using traditional construction methods. As stated by the contractor who proposed the use of ABC, "We knew that ABC would cost more, but we could make up the difference saving on lane rentals, building the crossovers, limiting excavation and reducing time and overhead." |
