Sound Transit is replacing the wooden single-track railroad trestle east of Freighthouse Square with a new, concrete double-track bridge. The new bridge will support increased passenger and rail capacity along the corridor and improve reliability for Amtrak passenger service. The existing wooden trestle would require structural upgrades within five years to support current and increased rail operations.
To replace the trestle, crews will demolish the current 0.65 mile-long wood structure and construct a new double-track rail bridge over South 26th and East G streets and crossover tracks. Other improvements include building an expanded passenger platform to accommodate Amtrak passenger trains, making minor street repairs, relocating some utilities, replacing retaining walls at both ends of the bridge, and upgrading railroad signals.
In 2008, voters approved the Tacoma Trestle Track and Signal project as part of the Sound Transit 2 ballot measure. The total Tacoma Trestle project budget is $115 million (2014 dollars). In 2013, Sound Transit received a $10 million grant from the U.S. Department of Transportation's Transportation Investment Generating Economic Recovery (TIGER) program. The project will accommodate three additional Sounder south line round trips by 2017 and completion of the Washington State Department of Transportation Point Defiance Bypass Project.
