Prior to the start of light rail service, the Puyallup Tribe of Indians proposed an extension of Tacoma Link to their new casino-hotel complex, approximately southeast of Tacoma Dome Station near Interstate 5. A study into the extension was commissioned in 2004 by the Puyallup Tribe, with Sound Transit finding that the project would cost and estimated $38 million to $72 million depending on which of the four potential routes were chosen. The study also projected that ridership levels would require a new fleet of two-car trains and longer platforms for the rest of the line, leading to increased costs. Two additional extensions to the west were also studied by Sound Transit for inclusion into a long-range plan, but were deferred due to their high costs. The Tacoma city government also proposed a network of streetcars in 2007, looking to emulate the Portland Streetcar system rather than extending Tacoma Link.
