On Nov. 9, Sound Transit posted an East Link update on the progress made so far and a look ahead at upcoming work. Construction has been underway for a few months, since the Interstate 90 center roadway closed in June.
To seismically retrofit the floating bridge and approach structures in advance of light rail construction, Sound Transit’s contractor has been focusing on preparing, mobilizing and beginning demolition along I-90. East Link will extend 14 miles from Seattle to Redmond. It is set to open in 2023.
Demolition work continues along the floating bridge, in the Mercer Island tunnel and at the station area while seismic retrofit work will begin along the East Channel Bridge. This winter, while work may not be visible on the floating bridge, work will be happening within the pontoons and I-90 tunnels in Seattle and Mercer Island.
Construction will become more visible in early 2018 as work on the station platform and both east and west head houses begins.
