The Valley Metro Light Rail transit system that serves metropolitan Phoenix has been expanded by 3.2 miles along 19th Avenue by Sundt and a joint venture partner.

 

The heavy civil construction project included coordinating major utility relocations, widening the roadway to accommodate the 40-foot-wide track alignment, and self-performing the concrete paving to support the new double tracks along the route. The team also installed the tracks, constructed three new train stations with passenger platforms, built a Park-and-Ride lot, constructed three traction power substations (which supply electricity to the trains), installed new intersection signals and crossovers, and built the concrete foundations for the overhead catenary system that feed electricity to the trains.

 

The Northwest Extension serves approximately 5,000 riders per day. In 2008, Sundt and its joint venture partner completed more than half of the original 20-mile “starter” section of the Valley Metro Light Rail transit system, plus the system’s maintenance and operations facility.
