Project Needs

WSDOT will repave the State Route 525 Spur (Paine Field Boulevard) from where it splits with SR 525 (Mukilteo Speedway) to just west of Boeing Access Road. This project will also repave SR 526 (84th Street Southwest) from Paine Field Boulevard to Mukilteo Speedway. These stretches of highway haven’t been repaved since 1999. Cracks, ruts and potholes have developed. This creates an uneven surface which allows water to pool on the roadway, reducing traction. Wet roads can also result in slower travel times as drivers reduce their speeds to handle the slick surface. Removing the old, worn out asphalt and replacing it with new pavement will provide safer driving conditions and extend the life of the highway. Westbound 84th Street Southwest will be reduced from two lanes to one. Bike lanes will be added in both directions on 84th, and crews will improve sidewalk connections for people of all abilities.

Why is westbound SR 526 (84th Street Southwest) being reduced from two lanes to one?

Looking at traffic patterns, the city of Mukilteo decided it was a more effective use of roadway space to add shared biking lanes in each direction of 84th Street Southwest between Paine Field Boulevard (SR 525 Spur) and Mukilteo Speedway (SR 525). The bike lanes are part of Mukilteo’s “By The Way” plan. To make room for the addition, a westbound traffic lane will be removed. Westbound was chosen because eastbound SR 526 has more truck traffic that struggles to make it up the hill, and there are fewer westbound commuters on an average day. A new shared use path will improve connectivity for the non-motoring public in Snohomish County.

Project Benefits

  • Safety: Repaving the highway removes existing cracks, ruts and potholes where pooled water can collect, causing cars to slide. This water can also freeze, creating pockets of ice on the asphalt. New pavement will also prevent future damage to the roadway.
  • Safety: A designated path on 84th Street Southwest (SR 526) reduces the risk of collision between automobiles and non-vehicular traffic.
  • Economic: Repairing aging asphalt is a cost-effective way to protect the roadway and increase its lifespan.
