Final girder to be installed on West Valley TRAX bridge

Written by 

Utah Transit Authority in the Salt Lake City area is scheduled to place the final girder on the new West Valley TRAX bridge over Union Pacific's Roper Yard Nov. 5. The bridge is the largest single structure on the West Valley TRAX line and its completion is an important milestone on the project. The West Valley TRAX Line will extend TRAX service from 2100 South Central Pointe station on the North-South TRAX line southwest to West Valley City Hall.

The Roper Yard TRAX bridge is 780 feet long and 46 feet wide with three spans over Union Pacific's Roper Yard. Each girder is approximately 10 feet tall. The largest span over the railroad is 330 feet long. The bridge approaches are constructed using Geofoam-a Styrofoam-like foundation material that speeds up construction and saves money by reducing settlement time.

TRAX will share the new bridge with a pedestrian/bike trail that will connect to the Parley's Trail.
