Project updates: East Link Extension

May 25, 2018

You've got rail! Rail delivery begins on Mercer Island

East Link construction has reached a milestone as rail has arrived on Mercer Island and is the first East Link project to do so. Approximately 15 miles of rail have been delivered to the work zone on Mercer Island. Approximately 28 miles (or 148,800 feet) of rail will be installed between the International District / Chinatown Station and the East Channel Bridge. Rail welding and grinding will begin in the coming weeks to prepare for installation. Check out some additional progress photos below.

Looking ahead

Structural steel has begun to arrive as the west head house will begin to take shape. In June and July, crews will post-tension the Homer M. Hadley Bridge, which will require overnight westbound closures. More information about these closures will be available in the coming weeks.

There will be no ramp or lane closures during the Memorial Day holiday, from 12 p.m. Friday, May 25, until 12 p.m. Tuesday, May 29. Planned closures will resume on Tuesday, May 29 at 12 p.m.

I-90 nighttime construction begins as early as May 29

Crews working for Sound Transit will begin overnight work on the I-90 floating bridge to prepare for post-tensioning work inside the pontoons. As early as Tuesday, May 29, for approximately three weeks, work will occur nightly from 5 p.m. until 5 a.m., Monday – Saturday. Crews will install steel tendons which will be used to post-tension the pontoons later this summer. Work will begin on the west side of the bridge, near Seattle, and will proceed east.

Post-tensioning is a method of reinforcing concrete with high-strength tensioned steel strands. Essentially, compressing concrete and pulling the floating bridge pontoons closer together, increasing the bridge’s lifespan. In June and July, crews will post-tension the Homer M. Hadley Bridge, which will require overnight westbound closures. More information about these closures will be available in the coming weeks.

Here's what you can expect:

  • Crews will work from 5 p.m. – 5 a.m. Monday-Saturday. (Work hours are subject to change)
  • Crews will install steel tendons inside the floating bridge pontoons. Ballast may also be removed or added to the pontoons during this time.
  • Broadband back-up alarms will be used to minimize noise.
  • Generators and lighting may be used and will be shielded to minimize noise and glare.
  • Work activities will be monitored to comply with City of Seattle noise ordinances.
