West Marginal Way SW / Duwamish Trail missing link

SDOT announced a decision for the Duwamish Trail missing link on West Marginal Way SW: Protected bike lanes will be installed after the West Seattle Bridge reopens in mid-2022.

While sooner would be better, it is good to have this commitment from SDOT to permanently improve safety for bike riders and vehicle drivers on West Marginal Way SW. Reducing the opportunities for reckless right-side passing by impatient drivers should reduce the frequent crashes that tie up traffic for hours and injure people using this route. WMW is an essential freight route. We understand the need to prioritize freight and to accommodate all others who must use this street.
Kudos to the SDOT Vision Zero team. They developed a creative plan and reached out and listened to all who depend on this street for transportation and for safe pedestrian crossing at the Duwamish Longhouse & Cultural Center.
This will fill in a missing link in the Duwamish Trail, a regional bike commuting and recreational route leading to the Alki Trail, West Seattle Junction, South Park, Georgetown, Green River Trail, Tukwila, SODO, Downtown Seattle, and the Mountains to Sound Trail. The route serves marginalized communities in the Duwamish Valley. This route is critical for all bike traffic between northern West Seattle and Greater Seattle at times when the Spokane Street Bridge is closed to bike traffic for inspections and repairs. The improvements will make the route safer for commuting by bike, especially in winter and at night, and more comfortable for people of all ages and abilities.

Biking to Bridge the Gap

Emily asked us how to ride her bike safely from West Seattle to work at the VA Hospital. Erin asked how to ride to UW Medical Center.  Travis is willing to commute on his new e-bike all the way to Green Lake. We are fielding many inquiries. Bike sales are taking off.  With alternate route traffic delays looming, Georgetown and South Park residents are fearful of gridlock, air pollution, and for the safety of their children walking to school. We know that using bikes instead of cars will help free up capacity on the remaining bridges. But we need a few improvements make it safe and efficient for these folks and many more people to bike instead of drive.

West Seattle Bike Connections with Duwamish Valley Safe Streets, Seattle Neighborhood Greenways and Cascade Bicycle Club sent a detailed proposal to the City yesterday, summarized here.

OUR GOAL

Mobility for West Seattle, SODO and the Duwamish Valley.

Keep people and goods moving safely across much lower-capacity bridges over the Duwamish while the West Seattle High-Rise Bridge is closed. Mitigate impacts on our communities. Honor Seattle’s commitments to equitable transportation, our environment, social justice, and economic vitality.

STRATEGIES

Encourage or incentivize as many people as possible to use bikes or transit, or both, instead of driving private vehicles. Accomplish this before the end of COVID-19 restrictions.

    1. Improve conditions to make it safe, efficient and comfortable for people to ride bikes and transit.
    2. Concentrate on safety and wayfinding for biking and bike/transit connections:
      • On key West Seattle bike routes to the Spokane Street bridge, and from the bridge on East Marginal Way S to Pioneer Square, Downtown, SODO Trail, and SODO light rail station.
      • On bike routes to the 1st Ave S bridge and South Park Bridge, and bike routes within South Park and Georgetown that are impacted by alternate route traffic and may also be needed for biking from West Seattle whenever the Spokane Street Bridge is closed.
      • On routes to and bike parking at the King County Water Taxi dock at Seacrest.
    1. Protect Neighborhood Greenway streets near alternate routes from cut-through traffic, to keep them safe for residents and for walking and biking by people of all ages and abilities.
    2. Ensure availability of bikeshare bikes. Provide bikeshare discounts and bike/e-bike financing to people with low incomes.
    3. Use up to 1% of the bridge repair cost for mitigation measures for bike and pedestrian safety and efficiency.
    4. Use advocacy groups like West Seattle Bike Connections, Duwamish Valley Safe Streets, Cascade Bicycle Club and Seattle Neighborhood Greenways to:
      • Identify opportunities to improve safety and wayfinding.
      • Provide route advice, route maps, bike buddy matching, bike trains and educational rides.
      • Connect people to good advice and local bike shops for selecting and maintaining bikes, including e-bikes.

RECOMMENDED WORK FOR STREET SAFETY

PRESERVE these already planned and funded projects on schedule: 
EXPEDITE these key Bicycle Master Plan high priority routes:
    • Sylvan Way SW / SW Orchard and east to Highland Park
    • Highland Park Way SW off street multi-use path
    • 1st Ave S Bridge to 1st Ave S safe route north from bridge
    • SW Roxbury  bike lanes without reducing traffic lanes
QUICKLY IMPLEMENT spot improvements for wayfinding and safe routes:
    • On Spokane Street Bridge routes at the Chelan 5-way intersection; on Fauntleroy Way and Admiral Way; on the “Nucor Trail” connection from Delridge to the Alki Trail; at Terminal 18 trail crossings on Harbor Island; on East Marginal Way; and on the connections to the SODO light rail station and SODO Trail.
    • On 1st Avenue South Bridge and South Park Bridge routes at the Duwamish Trail “missing link from the Alki Trail; on Highland Park Way at West Marginal Way; at rough rail crossings on the Duwamish Trail and in Georgetown; and on routes in Georgetown through SODO.
