In May 2001, a joint venture led by Kiewit Construction Company, a subsidiary of Kiewit Corporation was awarded this $1.28 billion design-build project. Completed in fall 2006, project personnel reconstructed 17 miles of two interstate highways while simultaneously adding 19 miles of new double-track light rail transit (LRT) line, including 13 new stations. In addition, the multi-modal project included the construction or reconstruction of 61 roadway bridges, 14 LRT bridges, 3 LRT tunnels, 400 utility relocations, drainage improvements, and enhanced pedestrian and bicycle access.
Unique aspects included highway and mass transit construction; public involvement and information programs; an environmental impacts plan; and Intelligent Transportation Systems to manage traffic flow and reduce incidents.
Mass. Electric Construction Co., a subsidiary of Kiewit Corporation, installed the traction electrification, signaling and communications systems, and a new Operations Control Center tying into the new and existing LRT lines.
The T-REX Project increases transit options, enhances safety, replaces aging infrastructure and significantly reduces travel time.
