Project overview
This project will repave, with Hot Mix Asphalt (HMA), and construct Americans with Disability Act (ADA) upgrades on State Route 525 from the SR 525 Spur, just north of Harbour Place, to 2nd Street. This project is subject to WSDOT’s Complete Streets requirements. Additionally, the paving project was awarded a $1.5 million dollar grant for construction that requires construction begin in summer 2026. We will be working to incorporate as much active transportation facilities as feasible with the paving construction, but due to the short timeframe to deliver the paver and ADA upgrades, it is likely some active transportation facilities needed to meet the complete streets requirement will be constructed by a later project.
What to expect
Summer of 2026, travelers can expect single and alternating lane closures and pedestrian detour routes on city side roads. Work will take place at night to minimize disruptions for ferry travelers.
Healthy Environment for All (HEAL) Act
This project is also subject to Washington's environmental justice law, known as the Healthy Environment for All (HEAL) Act. Environmental justice in Washington State, as provided in the HEAL Act, addresses disproportionate environmental and health impacts in all laws, rules, and policies by prioritizing vulnerable populations and overburdened communities, the equitable distribution of resources and benefits, and eliminating harm (RCW 70A.02.010)
This project will repave and construct ADA upgrades on SR 525 from SR 525 Spur Vicinity to 2nd Street in Mukilteo.
SR 525 will be repaved as part of WSDOT’s ongoing preservation program. This stretch of SR 525 was paved in 2000. The roadway is due for paving as the typical lifespan of HMA is 15 years. This is a popular route to and from the Mukilteo ferry with about 15,000 travelers using the road daily.
As required by 28 CFR Part 35, ADA upgrades will also be constructed to meet current ADA standards to the maximum extent feasible.
Community engagement
Listening sessions
Listening Sessions are being planned for fall 2024 to hear about transportation challenges and needs and transportation preferences. These sessions will include community-based organizations and other interested parties.
Online Open House and Survey
Community feedback will be sought during an online open house and survey planned for late 2024/early 2025.

Complete streets
SR 525 Complete Streets Report (PDF 7.8MB)
The Complete Streets legislation was passed in 2022, in Washington Senate Bill 5974. Using the WSDOT’s Complete Streets approach,
this project will go through a Complete Streets Pre-design phase to determine the SR 525 corridor cross-section between milepost 5.72 to 8.47. The cross-section includes lanes for cars, buses, and trucks and facilities for bicyclists and pedestrians, all in one plan. The pre-design phase of the project will include significant community engagement to understand the needs of tribes, overburdened communities, multimodal users, ferry passengers, residents, and other interested parties in the area.
The intent of the SR 525/ SR 525 Spur Vic to Mukilteo Ferry Terminal – HMA Paving and ADA Compliance - Complete Streets Pre-Design phase is to create a corridor that accommodates all users (pedestrians, bicyclists, transit users, and motor vehicle drivers) as well as provide improved connections to key destinations including the Washington State Ferries (WSF) Mukilteo Ferry Terminal, Sound Transit Mukilteo Sounder North station, parks, businesses, and neighborhood services. The public and interested parties will have opportunities to give input on the design of the new SR 525 bridge and SR 525 corridor within the project limits.
