Continued construction work at East 26th and East ‘G’ Street

Construction work for the Tacoma Trestle has been going on since spring 2016; as of the beginning of March, we have begun to work on the construction of the north concrete bridge.

Over the next three months, construction crews will have a lot of work going on in this area. During this time, for safety reasons, the contractor will be unable to reopen the East 26th and East 'G' Street intersection to vehicular and pedestrian access.

Construction work activity:

Pile driving has begun and should continue until all piles are in the ground for the north bridge. The progression of work will be west to east; crews will perform the work in a similar fashion to the construction of the south bridge. 

After completion of pile driving, the next step will be to construct footings and columns for the piles before pouring the cement and installing the falsework for the top bent caps (see picture).

Concrete pole diagram

After the cement column work progresses past the East 26th and East 'G' Street intersection, the contractor will be able to erect the second steel girder bridge that will span across the intersection. This work is anticipated to take place between mid-April and early May.

Following the installation of the steel bridge, construction crews will rebuild East 26th and East 'G' Street, installing necessary curbs, and finally repaving this heavily impacted area.

What to expect:

Access to businesses along East 26th St. will be maintained via East 'J' street.

The maintainance of alleyways and residential driveway access at all times.

Pedestrians will no longer have access through this area.

Traffic detour signs posted along the detour routes.

Pile driving work starts again

Once the bridge slide work is complete (Feb. 17-22), pile driving is anticipated to start near the intersection of East 'G'/East 26th Street as early as Feb. 24.

Pile driving uses a large crane to force the piles (poles) into the soil to provide foundational support for bridges or other large structures. Pile driving is loud and Sound Transit will monitor noise levels to gauge the safety of the work.

What to expect:

  • Pile driving operations can occur Mon. through Sat. between 7 a.m. and 4 p.m.
  • Equipment and materials will include a crane, trucks and piles
  • People will hear a metal-against-metal hammering noise as piles are driven into the ground

Pile driving will start at the intersection of East 'G'/East 26th street, and it will move east.

ATTENTION: No trespassing along the railroad right of way.

The East D Street entrance to the Tacoma Dome Station (Freighthouse Square) platform will be closed for 90 days (from Jan. 25th until Mar. 25th) due to construction on the platform by the Washington State Department of Transportation’s Amtrak Station project. For safety reasons, the construction zone is fenced off to prevent pedestrians from walking through the area. All passengers accessing the platform must do so through the breezeway at East 25th Street to get to/from East D Street.

Pedestrians are not allowed to go around the construction zone by walking on the tracks. Doing so is unsafe. It’s also considered trespassing and a violation of Washington state law. Signage and Sound Transit personnel will be available on the platform to assist customers during this temporary closure.

Phase 3 – Demolition of the existing steel girder bridge and the start of Sounder service on new south bridge structure

New double-track concrete bridge replacing 100-year-old trestle

From Feb. 17-22, Sound Transit's contractor will move the steel structure span, currently suspended across East 'G' Street, into place and weld it all together. After this work has taken place, train service will move from the old trestle onto the new bridge.

What to expect:

  • Construction activities: Various construction activities will be going on 24 hours a day during this track outage. Activities include, but are not limited to:
    • Removal of the existing track and signals.
    • Demolition of the existing concrete slab and the existing steel girder bridge.
    • Sliding the new steel bridge into place and welding all pieces together.
    • Installing new rails, wooden ties, ballast, and signals.
    • Running a test train across the south bridge to prepare for train service.
  • Equipment: Construction crews will have trucks and support equipment stationed in the area to help facilitate the work.
  • Access: Businesses along East 26th Street will be maintained via East 'J' Street; detour signs will direct traffic along the detour routes.
  • Work hours: 24 hours a day from Feb. 17 until Feb. 22.

Sound Transit will share details with riders in advance of the change through a variety of channels, including signage, social media and rider alerts. Sound Transit representatives will be on-site during the service change to help direct people to their connections. Riders can find information about the temporary change and sign up for alerts at http://www.soundtransit.org/SounderDisruption.

What is coming up next?

Phase 2: Currently underway

The second phase of the Tacoma Trestle project is underway. It consists of the construction of the steel girder that will support the train tracks across the intersection of East 'G' Street and East 26th Street. Once this work is complete, the steel girders will slide into place for permanent attachment to the new trestle. Next, the Sounders service and freight trains currently operating on the old trestle will transfer over onto the new bridge, and phase three will begin.

Phase 3: 1st Quarter – 2017

The next step in the Tacoma Trestle project will be the demolition of the old trestle. This phase should occur during early 2017. Also included is construction of a new south platform and extension of the existing north platform.

Phase 4: 2nd Quarter through the 4th Quarter - 2017

The final phase of construction will begin with a second round of pile driving. The pile driving for Phase 4 will be for the construction of the north half of the new trestle. Construction of this half of the trestle should last for six to eight months, with completion by the end of 2017.

Construction activity at East 'G' Street between East 25th Street and East 26th Street

Part of the steel girder that will support the railroad tracks above East 'G' Street and East 26th Street is in the process of being fabricated five feet off of the currently alignment. At the end of December, Sound Transit’s contractor installed a safety fence order to ensure pedestrian and vehicular safety.

What to expect:

  • Access to businesses along East 26th Street will be maintained via East 'J' Street.
  • Assess to alleyways and residential driveways will remain at all times.
  • Pedestrians will no longer have access through the construction area
  • Signs to reroute traffic will appear along the detour routes.

Continued street closure

The most impactful street closure for the Tacoma Trestle project is the closure of E 'G' Street to through traffic underneath the existing steel girder bridge. 

For public safety, crews will close the intersection during this time. Remaining work at the intersection includes the bridge slide, the demolition of the trestle in this section of the project, and the final phase of pile driving that will begin for the north half of the Tacoma trestle bridge. Our contractor will start at the west side of the trestle and work east. 

With the accumulation of all these construction impacts, it is our goal to mitigate the duration of this closure by closing the intersection of East 'G' and East 26th Street until the above mentioned work has taken place. The contractor estimates the intersection will reopen to through traffic around spring 2017.

South Platform construction

As part of the Tacoma Trestle work, Sound Transit is also construction a new south platform. The purpose of the platform is to allow for a maximum of passenger trains to serve the Tacoma Dome station at one time.

Over the past month, construction crews have been drilling the support beams into the ground. This will help stabilize the south platform.

What to expect:

  • Construction vehicles will be moving up and down the south platform, reshaping and cleaning up the slope
  • Crews installing underground utilities
  • The construction of the new wall and the platform, which includes installing the canopy and lighting
  • Work hours are 7 a.m. – 4 p.m., Monday to Saturdays
