Roadway deck progresses toward Montlake

Deck AerialNow that all 353 girders and 108 seismic isolation bearings are installed for the West Approach Bridge North, crews are moving along with pouring concrete for the bridge’s roadway deck. Over the past few months, 31 of 41 total deck sections have been poured. This week, crews plan to pour concrete on Wednesday and Friday.

This work is heavily weather dependent and may be postponed. The most up-to-date schedules will always be posted on our website.

In the weeks following, crews plan to pour one section of deck per week. They expect to complete the base of the bridge’s roadway deck by mid-April.

If you live near the construction site, note that all concrete pours are scheduled to begin at 8 a.m., but you may hear crews and trucks mobilizing as early as 6 a.m.

The new, 1.2-mile-long bridge linking Montlake and the new SR 520 floating bridge is expected to open to traffic by late summer 2017.

Recap of January's weekend closure of SR 520

Concrete MuncherDuring the weekend closure of SR 520 (Jan. 27-29), crews removed the remaining section of the old westbound SR 520 off-ramp that extended over the highway (pictured to the right). Crews also continued installing handrail along the pedestrian path between the westbound flyer stop and Montlake Boulevard.

SR 520: The Year in Review

Year In Review

The year just past was one of the biggest yet for the SR 520 Bridge Replacement and HOV Program. In 2016, we opened the world’s longest floating bridge (as declared by Guinness World Records), drew closer to completion of the West Approach Bridge North, and turned our attention westward with the final designs for the Montlake Phase of the project, which includes improvements along the SR 520 corridor in Seattle.

You can read all about this and more in the 2016 Year in Review newsletter on our website. You may have received this flier last week in your mailbox, but feel free to pass the link along to anyone who may be interested in the progress of this project and the work planned in Seattle in the coming years.
