It’s happening: Yesler Way to get new bike lane, closing critical gap in Seattle’s bike network | LEVY DOLLARS AT WORK  - SDOT Blog Seattle's historic Pioneer Square neighborhood is getting new protected bike lanes, closing a key gap in the city's bike network.

SDOT worked closely with Alliance for Pioneer Square to move this long-planned connection forward.

Read more about it here: sdotblog.seattle.gov/2026/02/26/p...

Building this missing piece to the city’s bike network wasn’t simple. The historic nature of Pioneer Square and the age of the infrastructure made adding modern bike and signal improvements complicated, requiring careful design and coordination.

A detailed map of Seattle's Center City bike network, showing existing bike routes in solid green, future connections in dashed green, and routes under construction in dotted orange. A zoomed-in inset highlights the waterfront area near Yesler Way, which runs east-west and connects the waterfront (Alaskan Way) to the downtown core. Key streets like 1st Ave, Alaskan Way, and Yesler Way are labeled, along with landmarks such as Seattle Center and Elliott Bay.

This project fills a gap in Seattle’s City Center Bike Network & creates a much-anticipated, safer connection between Pioneer Square, downtown, and the waterfront.

Construction officially began this week with underground work, and more visible changes on the street will follow in the coming weeks.

It’s happening! Yesler Way is getting a new protected bike lane from Occidental Ave S to the waterfront.

TONIGHT (2/26): One left lane of northbound I-5 will CLOSE between Olive Way and @sr520.wsdot.wa.gov from 10p to 4a Friday (2/27) for guardrail work.

This lane closure is just south of the Ship Canal Bridge, where two right lanes are closed for construction. Expect delays @seattledot.bsky.social

Seattle’s soon-to-be first roundabout on an arterial street gets its first curb ramp concrete pour!

It’s part of our project to help connect you to the new Pinehurst light rail station when it opens later this year.

A flagger will be on site to direct traffic. Pedestrian access will be maintained at all times via the Park Promenade. Check out our flyer at the link here for more information.

Additionally, Alaskan Way between the Elliott Way intersection and Virginia St will be intermittently reduced to one lane for alternating traffic during work hours, Monday – Friday, 9 AM to 5 PM .

To support the safety of all Waterfront Park users, people biking and scooting are asked to dismount their bikes and scooters when traveling through the park or use Alaskan Way to continue their travels.

This work requires a 24/7 closure of the bike lane between the Alaskan Way and Elliott Way intersection and Virginia St for approximately 2 weeks.

To improve access for those biking or scooting on the waterfront, we will be fixing puddles in this area of the bike lane which has come to our attention since this segment was opened.

A message from the Seattle Waterfront:

A segment of the waterfront bike lane will be closed near Pier 62 as early as February 25.

It was restored today. Thank you for reaching out. We're working on a more permanent solution.

Yes, we are concerned about that and plan to add additional signage there soon.

Thanks for the suggestion, I posted an incorrect map yesterday and wanted to alert you & others that there's been a correction.

From left to right: A detour route from eastbound Denny Way follows Boren Ave, then turns left onto Howell St, then right onto the I-5 on-ramp. Yale Ave is closed between Denny Way and Stewart St. No right turns are possible onto Yale Ave from Denny Way. Yale Ave is still accessible from westbound Denny Way via left turn or southbound Stewart St via left turn to access the I-5 on-ramp.

Hi Matt, just replying to let you know that I posted an incorrect map yesterday. The corrected version is below. Access to Yale Ave from westbound Denny Way and southbound Stewart St is not impacted.

We expect the closure to last until March 20.

We are monitoring signals and traffic volumes and will adjust them based on what we observe.

And yes, it's Howell St - not Howell Ave. Sorry. I stared at the map for too long.

The really important part is the detour, since this closure will close the right turn from Denny Way onto Yale Ave.
