Infrastructure Projects

Whether you're a kid or grandmother, you deserve to be able to enjoy the happiness and health benefits of riding a bike wherever you need to go.

Too many streets aren't safe enough for everyone to ride. Here at Cascade, we know we can do better. We have a vision for to connect Seattle's neighborhoods and the region's cities with protected bike lanes, neighborhood greenways, and bike paths that people of all ages and abilities feel comfortable riding.

That's why we do the in-house research and planning into the best practices for designing and engineer our streets to be safer. We set priorities for funding and building better infrastructure and meet with city, regional, and state planners and elected officials.  We build broad coalitions of businesses, organizations, and leaders. We train, mobilize, and celebrate bike activists. And we elect candidates to city, county, and state office who will support better infrastructure and laws for bicycling.

Cascade's current priority infrastructure projects:

  • Seattle
    • Securing funding to build 250 miles new protected bike lanes, neighborhood greenways and trails by 2024.
    • Center City Protected Bike Lane Network.
    • The Missing Link of the Burke-Gilman Trail in Ballard.
    • Westlake Protected Bike Lane.
    • Safe bikeways in Montlake and Portage Bay.
    • A safer Rainier Avenue.
  • Eastside
    • Cross Kirkland Corridor
    • Eastside Rail Corridor
    • Mountains to Sound Greenway

Definitions of Infrastructure

  • Protected bike lanes are on-street bike lanes with a physical barrier separating the bike lane from motor vehicle traffic. The barrier can include flower planters, concrete curbs, plastic bollards, jersey barriers, and parked cars. Protected bike lanes can be either one-way or two-way.
  • Neighborhood greenways are bikeways on slow speed, low volume residential streets. Greenways are more than just signed to provide bicyclists with wayfinding, greenways are engineered and designed to reduce vehicle traffic and speed on the street through speed bumps/humps, chicanes, roundabouts, curb bulbs, and priority stop signs (stops signs are removed from the bikeway and instead placed on the cross streets). Where a greenway crosses an arterial, the greenway is designed to better prioritize bicyclists and ensure their safety while crossing.
  • Bike boxes are green-painted rectangles (with a white outline) at intersections that provide a safe refuge for bicyclists to either cue ahead of cars or to make a two-stage turn. Bike boxes help increase safety for bicyclists by reducing right-hand hooks by cars and by helping bicyclists navigate tricky intersections, such as where there are streetcar tracks.
  • Cross-bikes are similar to crosswalks in that they warn drivers to expect bicyclists crossing an intersection. Cross-bikes are currently designed in several different ways, including parallel dashed lines with sharrows that extend a bike lane through an intersection, solid bright-green paint, and horizontal bars of bright-green paint (which is most similar to a white crosswalk).
  • Sharrows are large white bike symbols on the roadway that remind drivers that bicyclists may use the full lane. The term is the combination of two words: "share" and "ROW" (or "right-of-way"). Although in Seattle sharrows are often placed toward the right-hand edge of a street, bicyclists should not feel compelled to treat the "sharrowed space" as a bike lane; instead, they should feel free to take the full lane and ride in traffic, especially when in a narrow lane next to parked cars.
