SR 520 coffer cell wrap-up
Last week, another piece of heavy equipment made its way to Lake Washington, as a 660-ton steel coffer cell was barged to the floating bridge construction zone. This steel box will be attached to two pontoons on the lake so crews can complete repairs.
The coffer cell was launched off the barge into the lake yesterday morning, Nov. 26. Crews will begin attaching the cell to the end of Pontoon V early next week.
Check out our Flickr page for photos of the coffer cell’s launch into the lake, and visit our Pontoon and Floating Bridge Progress page for more info on how the coffer cell works.
Be prepared for post-Thanksgiving regional traffic
The holiday weekend begins with a downtown parade and the Apple Cup football game, and ends with a marathon through Seattle. Drivers should add extra time and be prepared for busy roads on Friday and lane and ramp closures on Sunday. Here are the details:
Friday, Nov. 29: The southbound I-5 off-ramp to Union Street will be closed from 8 to 10:30 a.m. Other downtown Seattle exits will likely experience heavy traffic as people make their way to the annual Macy’s Holiday Parade beginning at 9 a.m.
Friday, Nov. 29: Apple Cup at Husky Stadium, 12:30 p.m. kickoff. Expect heavy congestion near the University District on I-5 and SR 520 at Montlake.
Sunday, Dec. 1: The Seattle Marathon will affect traffic with lane and ramp closures.
- I-90 express lanes will be closed to all traffic from 5 to 11:30 a.m. when they will open in the eastbound direction.
- I-5 express lanes will be closed until 9:30 a.m., when they will reopen to southbound traffic.
- The northbound I-5 off-ramp to Lakeview Boulevard will be closed from 7 a.m. to 4 p.m.
- The westbound SR 520 exit to East Roanoke Street will be closed from 7 a.m. to 3 p.m.
In the Seattle area, drivers can check the latest roadway conditions with WSDOT’s online travel tools, such as the Seattle traffic page, the What’s Happening Now page, Twitter feed or mobile app.
Driver alert: new screen at the 520 west approach
Beginning today, westbound drivers will notice a new screen has been placed at the west approach near the construction area for the West Connection Bridge. This is to help reduce driver distraction while crews begin construction activities that are close to the highway.
Early next week, crews will begin impact pile driving in preparation for installation of the last ten piers for the new bridge. Since the new bridge connects to the existing approach, this work will be extremely close to traffic. Crews will work carefully to keep drivers safe, and the screen will act as a visual barrier to protect drivers.
Have you seen our construction videos?
Last week we published a suite of SR 520 construction tour videos on YouTube. These give you a behind-the-scenes look at the work we’ve done as well as a preview of what’s coming next. And if that’s not exciting enough, we’ve also published a pontoon’s point of view video of its trip through the Lake Washington Ship Canal.
