Overview
The T Line will extend 3.5 miles from its current terminus in the Hilltop neighborhood to add six new stations and bring service to Tacoma Community College.
With the TCC extension, the T Line will grow to 8.4 miles total with 18 stations, with further connections regionwide via the Link 1 Line at Tacoma Dome Station, forecasted to open in 2035.
Project timeline
In May 2026, the Sound Transit Board adopted an updated ST3 System Plan to bring the agency’s long-term financial outlook into balance.
The system plan includes funding for planning, design, and construction of the TCC T Line Extension with an opening date forecast of 2043.
Early planning and design work for the TCC T Line Extension will launch in 2027. This work includes:
- Assessing potential alternatives to the representative investments identified in the voter-approved ST3 Plan.
- Identifying ways to potentially accelerate the project timeline through innovative project delivery methods, approaches, and financing strategies.

From its current terminus near St. Joseph Medical Center in Tacoma’s Hilltop neighborhood, the TCC T Line Extension will turn west and add 3.5 miles of new service along S 19th Street.
A stop near Pearl Street will provide easy access to China Lake Park.
The T Line extension will provide an easy new transit option for Tacoma Community College students and staff.
