PLEASE NOTE: Starting January 14, 2019, we will retire the On the Move blog channel and all traffic advisory blogs will be posted on the SDOT blog channel.
The Green Lake and Wallingford Paving & Multi-Modal Improvements project has been out talking to the community about changes coming to Green Lake and Wallingford. Design is nearly complete, and we’ve made changes based on the design feedback we heard from the community earlier this year.
In July, more than 670 people joined us at drop-in sessions and many visited our online open house, to learn about streetscape improvements and give feedback.
In review of design and construction planning, we heard support for our general safety and mobility goals, and some suggestions for changes. We’ve summarized everything we heard and our response to the feedback; for details, read our Feedback and Action Plan: What We Heard and What We’re Doing document!
Improving safety for people walking on N 40th St | We’re adding rapid flashing beacons and repairing some stretches of sidewalk on 40th.
Reviewing east-west bike connections in Wallingford | We’re taking a step back to reconsider the design for bike improvements on N 40th St. In the coming months, we’ll evaluate other potential improvements to east-west bike connections in Wallingford.
Evaluating options for people walking and biking through the N 50th St, Stone Way N, and E Green Lake Way N intersection | We’re looking at ways to make improvements at this intersection by clearly marking crossings and improving visibility and sightlines.
Partnering with Seattle Parks and Recreation to explore an alternative to the planned bike improvements on Green Lake Way N | Our original design included a new signal on Green Lake Way N at N 52nd St. We’re now partnering with Seattle Parks and Recreation to explore transforming a portion of the planting strip bordering the Lower Woodland Parks Playfield parking lot into a 1-way protected bike lane.
Making the NE Ravenna Blvd, NE 71st St and E Green Lake Way N intersection more predictable | We’re squaring up this intersection as much as possible by adding curb bulbs and widening the west side sidewalk. We’re also adding a rapid flashing beacon one block south of the intersection.
Improving safety and visibility at intersections | We’re adding “no parking” signs 20 feet from all intersections in the project area; on the north side of N 80th St on either side of the Ashworth Ave N intersection, we’ll add paint and post curb bulbs to improve visibility.
Reducing speed limits to improve traffic safety for all | We’ll post a 25 MPH speed limit around the east side of Green Lake, which is a reduction from the current 30 MPH speed limit.
We’ll continue to engage you this fall and next year as we prepare for construction. This includes opportunities for public comment in early 2019 regarding bike improvements on N 40th St.
We anticipate completing the design by the end of 2018, beginning construction in late spring of 2019, and completing the project in 2020. For more information, please visit our project webpage.
What do you do when the city experiences three consecutive days of 85+-degree weather?
A. Drink a lot of water
B. Cool off your britches with a pool dunk
C. Cool off moving bridges with a water flush
D. All of the above
Admittedly, any of these answers is right – though our Roadway Structures bridge crews focus on “C”. That’s because temperature changes cause steel and concrete to expand and contract, a potential problem for bridges that open and close for passage of marine vessels. Too much expansion can create pinch points, where bridge sections can rub – and therein lies the rub, and reason for the flushing.
With this week’s high temps, the cooling truck (like a calming goat, only different) was out Thursday, at all three Ship Canal bridges – University, Ballard, and Fremont – consecutively. The water flushing operations are scheduled when Seattle experiences 2 – 3 consecutive days of at least 85-degree heat. Lucky for us, it didn’t get as hot as THIS looks…
Thanks to everyone for your patience during those 5-10-minute bridge closures! If temps creep up again, expect to see moving bridge gates down, just briefly, for that cooling/flushing truck and our team to work some misty magic!
In case you haven’t heard, the Lower Spokane St Bridge (a.k.a. West Seattle lower bridge) is open to all pedestrian, bicycle and vehicle traffic! The swing bridge went into its ‘open for marine vessels’ position last Wednesday at 8 PM, with an expected week or more to get it back online. The key to pulling it together? A spare!
The SDOT Roadway Structures team thinks about future needs and had a spare piston assembly stored in case the swing bridge ever lost its swing. Like a spare tire, the spare hydraulic cylinder got people up and traveling again, much sooner than it might otherwise take to fix a leaking piston assembly.
The spare assembly is a lot to love, about 15 tons, and took a special heavy duty forklift to move it. Thanks to United Motor Freight, Inc, located right next to the bridge, and President Jeff Landstrom, for making the emergency response vehicle available!
Around lunchtime today, Roadways Structures crews completed several test openings, with the installed spare, then picked up all the traffic control and detour signage…to swing back into business! That means the bike shuttle put in place during bridge repairs, provided its unceremonious last operation during this morning’s commute.
Thank you to everyone for your patience and understanding—and crews for your 12-hour shifts! More details to come on the originally identified problem when the damaged piston assembly is inspected later this week. Work has instead focused singularly on the efficient opening of the Spokane St Bridge, as a priority for travelers.
Today, the Roadway Structures crew is moving a 15-ton replacement cylinder into its exact place, inside the west shore pier house of the W Seattle Lower Bridge. The bridge was swung out to its marine vessel position last Wednesday, to further investigate a hydraulic fluid leak.
It’s no simple task to maneuver replacement parts as heavy as the combined weight of two elephants. The nearly 30,000-pound cylinder must be installed per specific controls, right down to cleaning it, along with reconnecting hydraulic oil lines, rewiring electrical conduit, etc.
There’s also continuous monitoring and testing along the way (not of the elephants; rather, operation of the 15-ton replacement cylinder). It all means there are several more days of hard work ahead.
On Saturday, the team worked a 4th consecutive 12-hour day, pulling the huge, damaged piston assembly out of its tightly placed spot, and delivering the new one to just inside the pier house dome. With such long hours and critical work, the team rested Sunday to ensure both a safe and successful effort kicking off again this morning.
The damaged piston assembly cylinder will be inspected in detail locally, to determine to cause of its hydraulic fluid leak.
The Spokane St Swing Bridge, a.k.a. W Seattle Low-Level Bridge over the Duwamish River, remains out of commission, potentially through the end of the week. We expect to know more tomorrow, June 26, 2018.

SDOT is advising travelers that work in the the northbound right lane of the Ballard Bridge has been rescheduled for a later time. Check back for times and dates.
SDOT advises travelers that the SW Spokane St Swing Bridge will be closed to marine traffic on Thursday, December 8, for approximately four hours from 8 a.m. to 12 p.m. for maintenance.
The date and time was picked to minimize the impact to marine traffic. Vehicle traffic across the bridge will not be impacted by this work.
Questions or concerns about the closure can be directed to Paul Elliott, SDOT Community Relations, (206) 684-5321 or firstname.lastname@example.org.

SDOT is set to begin repaving Roosevelt Way NE from NE 65th St to the south end of the University Bridge. Construction is scheduled to begin Monday, March 14, and is expected take six to eight months to complete. The contractor will remove the top several inches of asphalt, make any needed repairs to the underlying road base, and then repave with new asphalt. SDOT appreciates the public’s patience while this work is being completed.
Additional project elements include:
The project has been divided into five work zones. The contractor is required to substantially finish the work on one zone before moving onto the next, with the exception of work on the University Bridge which may overlap with other zones. The contractor, Jansen Inc., will start with the northern most zone and work south, with each zone expected to take about 8 weeks to complete.
Roosevelt Way NE will remain open to traffic throughout construction. Two lanes of traffic will remain open during the morning (7 – 9 a.m.) and afternoon (3 – 6 p.m.) commutes. At other times, the contractor may reduce traffic to a single travel lane. Access will be maintained to all neighborhood shops and restaurants, and SDOT encourages the community to continue shopping and dining at businesses during construction.
Regular hours of construction will be Monday through Friday, 7 a.m. to 5 p.m. Night and/or weekend construction is only expected for work on the University Bridge.
Work on the University Bridge will require its full closure to vehicular, bike, and pedestrian traffic for three weekends. On those dates, traffic will be detoured to the Montlake Bridge. The exact dates of these closures have yet to be determined, but will not occur on any weekends with major community events (i.e. Opening Day of boating season, University Street Fair, and University of Washington graduation) and will be coordinated with other major planned road closures.
Construction impacts include:
