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.
Sound Transit will construct the new bridge without significant disruptions to ongoing Sounder service. Construction will occur in phases. Crews will build the southern track of the new bridge, reroute train service to the newly built bridge and then demolish the existing trestle. 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 $160 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.
