Construction begins in Seattle

Construction activities for the West Approach Bridge North will become more visible as this major component of the SR 520 Bridge Replacement and HOV Program gets underway. Activities to expect this month include:
• Installation of field trailers

Upcoming closure: Bellevue Way and SR 520 ramps Oct. 3 to 6
Crews will close all lanes of Bellevue Way between 103rd Avenue Northeast and Lake Washington Boulevard, including the SR 520 on- and off-ramps at Bellevue Way and the intersection with Northup Way, from 10 p.m. Friday, Oct. 3 to 5 a.m. Monday, Oct. 6.

All lanes and sidewalks of Bellevue Way will be closed while crews install drainage on the Bellevue Way roadway and SR 520 ramps. Access to neighboring businesses will be maintained via a signed detour. Access to Points Drive Northeast will be maintained from southbound Lake Washington Boulevard. All ramps and roadways will reopen by 5 a.m. Monday, Oct. 6.
Upcoming closures: Westbound SR 520 off-ramp to Lake Washington Boulevard
Overnight, weekday closures of SR 520’s westbound off-ramp to Lake Washington Boulevard will occur for the next few months as construction kicks into high gear for the West Approach Bridge North. These overnight closures also will involve a single westbound lane of the highway across Foster Island. The off-ramp and lane closures are needed to allow the delivery of construction materials for the new bridge.

These overnight closures will start at 10 p.m. on Sunday, Monday, Tuesday, Wednesday and Thursday nights, with the westbound off-ramp and lane reopening at 6 a.m. the following mornings. The first week of closures starts this Sunday night, Oct. 5.
Pontoon watch: More pontoons on the move!

With 57 out of 77 pontoons needed to build the new floating bridge already on Lake Washington, crews will be towing several more pontoons to the lake over the next week. Beginning today, Wednesday, Oct. 1, a flotilla of tugboats began escorting two large, longitudinal pontoons and two smaller, supplemental pontoons from Aberdeen. They should arrive on Lake Washington late this week and over the weekend, pending favorable weather off the coast. Three smaller pontoons will also be floated up from Tacoma late this week. When this latest fleet of constructed pontoons arrives, we’ll have 64 on the lake.

The WSDOT website has web tracking tools and prime pontoon spotting locations should you want to follow the latest pontoon migration. If you catch a photo of the pontoon arrival this weekend, post it to Twitter and tag @WSDOT_520.
