JCM Northlink LLC is a joint venture formed by Jay Dee Contractors of Livonia, MI, Frank Collucio Construction Company of Seattle and Michaels Corporation of Brownsville, WI. The contract concerns 3.4 miles (5km) of twin light rail tunnels between Husky Stadium at the University of Washington and the Maple Leaf Portal near Northgate. In addition to the twin tunnels, the contract includes digging the underground stations in the Roosevelt and U District neighborhoods and excavating 23 cross-passages.

This is the largest construction contract Sound Transit has ever awarded. The work is scheduled to begin this fall and last just over four years.

JCM recently completed mining the light rail tunnels between downtown Seattle and Capitol Hill Station as part of Sound Transit’s University Link project.
