New SR 520 floating bridge taking shape

SEATTLE – The new State Route 520 floating bridge has begun its march across Lake Washington. Late last week, construction crews completed the first joining of two immense, concrete pontoons that will support SR 520 as it crosses the water.

Contractor crews working on the SR 520 Floating Bridge and Landings Project used 80 bolts, each 16 to 20 feet long and close to 800 pounds, to secure Pontoon V to Pontoon W near Lake Washington’s Medina shore. …read more

More State Route 520 floating-bridge pontoons arriving at Lake Washington

SR 520 Bridge

SEATTLE – More pontoons for State Route 520’s new floating bridge are about to arrive in Lake Washington.

The first of two supplemental pontoons being towed this week from Tacoma to Lake Washington was scheduled to reach the Hiram M. Chittenden Locks late this afternoon or early evening, Wednesday. Tug boats then will guide the massive concrete box through the Lake Washington Ship Canal before reaching the lake’s western shore. A second Tacoma-built supplemental pontoon is scheduled to arrive Thursday afternoon.

“We’re well past the halfway point with pontoon construction” said Julie Meredith, director of the Washington State Department of Transportation’s SR 520 Bridge Replacement and HOV Program. “We’re seeing strong progress in every phase of the highway program.”

The two pontoons arriving this week will be the 31st and 32nd pontoons towed to Lake Washington as part of construction of the new floating bridge. To date, 46 of the new bridge’s 77 pontoons have been constructed.

Six additional pontoons under construction in kbkw.com/tag/aberdeen” title=”View all articles about Aberdeen here”>Aberdeen are scheduled to be completed this spring. Other already-built pontoons now moored in kbkw.com/tag/aberdeen” title=”View all articles about Aberdeen here”>Aberdeen will be towed to Lake Washington later this spring.

Meredith noted that construction of the floating bridge’s 766 concrete deck panels began in February in Kenmore and that work on the Eastside Transit and HOV Project will wrap up later this summer, just as construction begins on a new, 1.1-mile-long bridge linking the new floating bridge with Seattle’s Montlake neighborhood. She also pointed out that the interim West Connection Bridge should be completed this fall, while the new floating bridge is scheduled to open in spring 2016.

You can find more online about the different types of SR 520 pontoons and track the status of their construction. You also can track tugboat Terilyn and view the general Puget Sound location of the pontoons on their trip from Tacoma to Seattle. A map of suggested viewing locations along the ship canal also can be found online.

Additional information about the SR 520 Pontoon Construction Project also is available online.

About supplemental pontoons
Supplemental pontoons flank either side of the floating bridge to give the structure added stability and flotation. The supplemental pontoons are 98 feet long, 28 feet high and 50 to 60 feet wide. Their weight ranges between 2,650 and 3,000 tons. By comparison, the bridge’s longitudinal pontoons, which lie directly under the bridge deck, are 360 feet long, 75 feet wide, 28.5 feet tall, and weigh 11,000 tons.

WSDOT recaps 2013 pontoon progress, raises 12th man flag for Seahawks

Crews working to build the new SR 520 floating bridge show their support for the Seahawks at the construction work zone in Medina.

The Washington State Department of Transportation is looking back at 2013, and tells KBKW crews made major progress building the new SR 520 corridor last year. From multiple pontoon float-outs in Aberdeen and Tacoma to nearing completion of the highway’s Eastside enhancements to preparing for the next phase of construction in Seattle, the past year was busy.

The department has compiled all the 2013 highlights in a year-in-review newsletter. You can find several notable accomplishments “By The Numbers,” from bridge anchors set on the bed of Lake Washington (58) to girders set for new Eastside overpasses (more than 300!). You’ll also see the key milestones reached each month, from January through December.

2014 promises to be just as busy. This spring, the fourth cycle of completed pontoons from Aberdeen is expected to float out. In the summer, the new Eastside corridor should open to drivers, and construction is set to begin for the highway’s next phase in Seattle, the West Approach Bridge North. Bridge assembly will continue all year on Lake Washington, as pontoons are joined to one another to form the new floating bridge.

Crews working on the new SR 520 floating bridge took a brief pause on Jan. 14 to show their spirited support of the Seattle Seahawks and their playoff run. Workers stood atop a pier for the new east approach bridge structure in Medina and proudly draped the “12th Man” flag. Best of luck to the Seahawks this weekend as they take on the 49ers at Century Link field. Go Hawks!
