Be advised: full closure of SR 520 this weekend for construction
SR 520 will be completely closed in both directions this weekend. The closure runs from 11 p.m. Friday, Oct. 17 to 5 a.m. Monday, Oct. 20, between Montlake Boulevard and I-405.

Crews will make good use of this closure. Their construction agenda includes beginning to dismantle the “Ramps to Nowhere” near the Arboretum, beginning construction of the 1-mile-long temporary work bridge that will serve as a staging platform for the West Approach Bridge North (WABN), and highway lane striping on the Eastside. Ramp demolition and pile installation for the temporary work bridge can be noisy depending on how far away a home or business is from the activity. To limit neighborhood disturbance, typical hours for pile installation will be between 8 a.m. and 5 p.m. on weekdays, and 9 a.m. and 5 p.m. on weekends. Ramp demolition, which can involve concrete saw-cutting and jackhammering, may occur up until 10 p.m.
Meanwhile, 108th/112th Avenue Northeast will be closed throughout the weekend between 108th Avenue Northeast’s eastbound on-ramp to SR 520 and Northup Way. The 108th/Northup Way intersection will also be closed nightly over the weekend so crews can install striping on local streets around the intersection. Details are below:
Weekend-long closure of SR 520 Corridor from Montlake Boulevard to I-405
• 11 p.m. Friday, Oct. 17 to 5 a.m. Monday, Oct. 20
Weekend-long closure of 108th/112th Avenue Northeast
• 11 p.m. Friday, Oct. 17 to 5 a.m. Monday, Oct. 20
Overnight closures of 108th Avenue Northeast and Northup Way intersection
• 11 p.m. Friday, Oct. 17 to 9 a.m. Saturday, Oct. 18
• 9 p.m. Saturday, Oct. 18 to 9 a.m. Sunday, Oct. 19
• 9 p.m. Sunday, Oct. 19 to 5 a.m. Monday, Oct. 20
So if you need to travel between Seattle and the Eastside, make alternate plans to avoid heavy traffic. I-90 will be open. Track this and future closures on our @wsdot_520 Twitter account and on the SR 520 website’s Orange Page.

West Approach Bridge North breaks ground Wednesday

WABN groundbreaking

Lending a hand with the start of demolition of the never-completed “Ramps to Nowhere” in Seattle were, from left, Seattle City Councilmember Tom Rasmussen, FHWA Washington Division Administrator Dan Mathis, SR 520 Program Administrator Julie Meredith, Gov. Jay Inslee, King County Executive Dow Constantine, U.S. Rep. Jim McDermott, State Rep. Judy Clibborn, and State Transportation Secretary Lynn Peterson.

Under cloudy but dry skies, WSDOT broke ground Wednesday, Oct. 15 on the next major project of the SR 520 Bridge Replacement and HOV Program: the West Approach Bridge North (WABN). The ceremony took place atop the R.H. Thomson “Ramps to Nowhere,” which will be removed to provide more public open space for visitors to the Washington Park Arboretum. On hand for the ground-breaking were a number of federal, state and local elected officials, including Gov. Jay Inslee and U.S. Congressman Jim McDermott, along with WSDOT staff and representatives from the lead contractor, Flatiron West, Inc.
When WABN opens – scheduled for summer 2017 – drivers and bus riders will for the first time be able to travel in a transit/HOV lane between Seattle and the Eastside. Bicyclists and pedestrians, too, will have their own dedicated path across Lake Washington.
We have a WABN-specific email newsletter for those who want to stay current on local, neighborhood-specific construction activities happening in Seattle. Sign up for the WABN e-mail list by entering your email address and then, under the “Construction Reports” section, selecting “SR 520 West Approach Bridge North Project”.

Win a piece of the "Ramps to Nowhere"

The R.H. Thomson “Ramps to Nowhere” are being dismantled as part of the West Approach Bridge North construction. We are celebrating this quirky chapter in Seattle transportation history with a Twitter haiku contest. The winners receive an actual piece of the Ramps to Nowhere!

Between Thursday, Oct. 16 and midnight Monday, Oct. 20, tweet a haiku about the “Ramps to Nowhere.” Include the hashtag #520haiku and make sure to follow the @WSDOT_520 Twitter account. On Oct. 21, three Twitter users who contributed a creative haiku and follow the 520 Twitter account will each win a piece of the "Ramps to Nowhere," taken from the ongoing demolition work.

Just think - a piece of historic concrete rubble, complete with certificate of authenticity! Seattle history buffs and transportation geeks, we're looking at you.

A reminder: a haiku is a three-line poem with lines of five, seven, and five syllables.
