Safety for West Marginal Way SW

With Duwamish Valley Safe Streets, we support SDOT’s proposal to add a two-way protected bike lane on West Marginal Way SW from West Marginal Place SW to the  crosswalk at the north end of the Duwamish Trail.

This will fill in the missing link in the Duwamish Trail, a regional bike route leading to the Alki Trail, West Seattle Junction, South Park, Georgetown, Green River Trail, SODO, Downtown Seattle, and the Mountains to Sound Trail. The route serves marginalized and underserved 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.

A significant benefit of the protected bike lane will be to improve traffic safety for all road users by slowing down speeding southbound traffic on West Marginal Way SW.

Crashes are frequent and severe. Median speeds were in the mid-40’s and did not come down after speed limits were lowered to 30.  Now speed radar signs are up, resulting in only about a 5 mph reduction. There is no congestion problem southbound due to lane capacity. There is a speeding and reckless driving problem, causing crashes and making it treacherous to cross on foot. Traffic congestion only occurs at the south end at the Highland Park Way intersection, where the backup from the First Avenue South Bridge begins. Along most of West Marginal Way SW, frantic drivers are rushing to get into the traffic jam as fast as they can. To hurry up and wait. Making more of the north end consistently one lane will allow drivers who travel at or near the speed limit to control the speed of all traffic, without any effect on throughput across the bridges. The bridges are the choke points, not the street.

For the short distance between the Duwamish Trail crossing and the Duwamish Longhouse & Cultural Center, we support SDOT’s option to allow parking in the curb lane north of the new signal and crosswalk. This will eliminate the current illegal use of the sidewalk area for parking that blocks pedestrian access.

Port of Seattle and Seattle Freight Advisory Board members are concerned about losing a traffic lane and about truck maneuvering at drives. We support their goals for good, efficient truck routes including on West Marginal Way SW. Our members and our neighbors are employed by these industries, and we all depend on them. We support SFAB’s request to maintain traffic lane width meeting standards for this Major Truck Street. However, we think the concerns about the PBL are not justified. Some industrial users also want lower traffic speeds, to help them get in and out of their driveways safely. Making the southbound direction continuously one lane from the Chelan intersection to the Duwamish Longhouse & Cultural Center will eliminate the Freight Board’s concerns about traffic merging from two lanes to one approaching SW Alaska Street.  If it turns out we are mistaken and SFAB’s fears are realized, the PBL would be easily reversible. If it turns out we are correct, this would help tame a free-for-all speedway into a street that prioritizes freight for industries and the seaport, but also safely accommodates people on bikes and walking as well as people driving personal cars and trucks.

Building a sidewalk where it is missing on the west side will provide a safer, more comfortable walking route from the nearest bus stops on SW Spokane St and on Delridge Way SW to the industrial employers and the Duwamish Longhouse & Cultural Center. However, sidewalks are not a safe substitute for protected bike lanes in the roadway, due to narrow width and poor sightlines at driveways where buildings are built to the property line at the street. Some have suggested cutting all the street trees to widen the sidewalk to the curb. Cutting more than two dozen healthy street trees would be contrary to City policy and would put cyclists just inches away from the most reckless drivers passing traffic on the right at speeds often exceeding 50 mph, making the route less safe.

We also appreciate the ongoing community outreach and engagement to make this work responsive to the needs of all people traveling on this important corridor.

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.

SODO Arena EIS – this affects bike connections from West Seattle

Arena Draft EIS came out to no fanfare in August. The proponents’ preferred SODO scheme vacates public streets, and impacts our bike routes from West Seattle to downtown and Beacon Hill, to say nothing of freight traffic and shipping, bus routes and car traffic.  Comments due by September 30.

At first glance, it is predictably and sadly lacking in evaluation of the traffic impact for pedestrians, bikes, cars, trucks, buses, and trains. They  have no b-ball team right now, so this will be easy for the proponents to slip by the citizens of Seattle unless we read it critically and comment or appeal it. If you are interested in a group response, please comment here or send a message. Land use and environmental attorneys wanted!  We need serious analysis and mitigation proposals.
