Bell St Protected Bike Lane

September 2019

What's happening now?

We are designing a two-way protected bike lane on the north side of Bell St between 5th Ave and Denny Way. The protected bike lane will connect bicyclists from Denny Way to the protected bike lane on 2nd Ave via Bell Street Park.

Project Overview

Protected bike lanes and signal upgrades in downtown Seattle can improve safety for everyone and connect pieces of a center city bike network. We've made a commitment to build out a network spine by 2020 to make biking a real choice and calm traffic as more people compete for limited street space.

As a nonarterial street with a gentle grade, Bell St is an ideal connection between downtown, Belltown, and South Lake Union. This project includes a two-way protected bike lane, concrete curb barriers with ground plane landscaping, and bike lane markings on Bell St between 5th Ave and Denny Way. Additional traffic calming measures will be implemented in Bell Street Park and bicyclists will be able to ride both ways, no bicycle facility markings will be made in the park. Bicyclists will have an all ages and abilities network that will connect the 9th Ave N protected bicycle lane to the 2nd Ave protected bike lane. 

This project's goals stemmed from the Bell Street Concept Plan. It aims to create a pedestrian-focused and cohesive corridor along Bell St.

Project Design

Our project design includes bike facility and signal and channelization changes. This project area connects to the wider bike network in the center city.

Design elements include:

  • New two-way bike lane on the north side of Bell St, between 5th Ave and Denny Way*
  • Bell St to rechannelize to one vehicular through lane between Denny Way and 5th Ave, with right turn lanes at 7th and 6th Ave
  • Concrete curb barriers with ground plane landscaping between two-way bike lane and vehicular travel lane
  • Vehicular traffic will not be able to enter Bell St from 5th Ave, except for emergency vehicles
  • King County Metro Bus stops and layovers along Bell St will be relocated with the start of construction
    • Bus routes will no longer operate through Bell Street Park
    • For updates on the permanent reroute of buses, please visit King County Metro's website
  • Parking removal on north side of Bell St between Denny Way and 6th Ave

*An interim bike facility on the north side of Bell St from 7th Ave to Denny Way will be designed and installed by Amazon in late 2019.

This project will have minor impacts to Bell Street Park located between 5th Ave and 1st Ave:

  • Minor revisions to signs and markings at intersections of Bell St with 2nd, 3rd, and 4th Avenues that will require permanent changes within Seattle Parks & Recreation property:
    • New stop signs and stop bars at 3rd Ave and 4th Ave to replace traffic signal for westbound motorists
    • New signs at 3rd Ave to clarify that westbound traffic must turn
  • Minor changes within Bell Street Park have been determined to be de minimis under Section 4(f) of the U.S. Department of Transportation (USDOT) Act of 1966. Compliance with Section 4(f) is required for projects receiving federal funding
  • Changes at Bell St and 5th Ave to provide an east-west connection for bicyclists
    • No right turn from 5th Ave onto Bell St
    • New bike crossing ramp and signal heads at 5th Ave to connect the protected bike lane and Bell Street Park

What are protected bike lanes?

A protected bike lane is an exclusive bike facility that combines the user experience of a separated path with the on-street infrastructure of a conventional bike lane. A protected bike lane is physically separated from motor traffic and distinct from the sidewalks.

These lanes have different forms but all share common elements - they provide space that is intended to be exclusively or primarily used for bicycles, and are separated from motor vehicle travel lanes, parking lanes, and sidewalks. Learn more at our protected bike lane page.
