ArrowWest Mesquite Interchange Showcase

Accelerated Bridge Construction & Prefabricated Bridge Elements and Systems

Mesquite, NV
January 10 – 11, 2012

This winter, the Nevada Department of Transportation will replace two bridge structures on Interstate 15 in Mesquite, Nevada as part of the Mesquite Design-Build Project. Join us to watch Nevada’s first bridge slide and learn about the exciting innovations behind its design and construction including accelerated bridge construction (ABC) techniques.

The current diamond configuration of the I-15 interchange 120 in West Mesquite will be updated to a roundabout interchange. In addition, the City of Mesquite’s local street of Falcon Ridge Parkway is in need of widening and improvement. Falcon Ridge Parkway is currently a two-lane road, but current and future traffic demands require that it be widened to a five-lane section.

Widening Falcon Ridge Parkway under I-15 poses one significant problem: The bridges over Falcon Ridge Parkway are not wide enough to accommodate a wider roadway, which means the existing I-15 bridges must be replaced.

In order to limit public impacts, the project team is using a design and construction plan utilizing ABC techniques to solve challenges posed by this project. Hollow-bar soil nails (HBSNs) were used to support the existing structure while the permanent foundations were constructed underneath the existing bridge. New superstructures were constructed adjacent to the existing bridges on temporary foundations. Precast/pre-stressed concrete girders and partial depth precast deck panels were utilized to decrease construction time. Each I-15 bridge will then be demolished, and the new bridges will be slid into place overnight using hydraulic jacks and Teflon rails along with a common household item: liquid dish soap for lubrication. Once the bridges are in their permanent positions, the roadway paving will be completed. This entire process will take place during a 56-hour period for each bridge, during which time I-15 traffic will be diverted using the freeway ramps.
