Utah Transit Authority completes double-track project


When Utah Transit Authority (UTA) opened its TRAX light-rail system in 1999, the line became a popular choice for area commuters. But the system quickly became a victim of its own success, as a single-track bridge became a main bottleneck on the mostly double-tracked system.

"We were dealing with a single-track bridge crossing Interstate 215, with the north and south lines sharing track time," said UTA Project Manager James Webb. "That increased headway times between vehicles and degraded service efficiency along the line."

Last month, that problem was solved when UTA completed a project that double-tracked the bridge. Now, trains can run in both directions simultaneously.

The project’s engineer, DMJM+HARRIS, coordinated design criteria with UTA and Utah Department of Transportation, which partially owns the right-of-way. Engineers also completed the project while maintaining passenger service at all times, according to DMJM+HARRIS.
