Downtown Seattle Transit Tunnel [SEP] Planning, funding and design
The Downtown Transit Project subcommittee unanimously approved Metro recommendations that would reduce the number of bus tunnel stations from six to five, saving $35 million, as well as opting for tunnel boring machines for the 3rd Avenue segment to minimize surface-level disruptions that would be present from cut-and-cover excavation. Stations would be located at Union Station south of Jackson Street, under 3rd Avenue and James Street, under 3rd Avenue and University Street, at the Westlake Mall and at 9th Avenue and Pine Street near the Washington State Convention Center. The Metro Council approved the station sites and use of tunnel-boring machines in July 1985, proceeding with final design by approving a $25.9 million contract with Parsons Brinckerhoff for engineering work related to the project.
