T-REX Project

T-REX
Location: Denver, CO

In May 2001, Southeast Corridor Constructors, a Kiewit-led joint venture, was awarded the Transportation Expansion (T-REX) Project. This $1.3 Billion design-build project involved reconstructing 17 mi. of two interstate highways while simultaneously adding 19 mi. of new double-track light rail transit (LRT) 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 improved pedestrian and bicycle access.

Unique aspects of the project 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 installed the traction electrification, signaling and communications systems, and a new Operations Control Center tying in the new and existing LRT lines.

The T REX project will increase transit options enhance safety replace aging infrastructure reduce travel time and congestion on nearby arterial streets, and support growing residential, and commercial areas served by the
Southeast Corridor.
