Project Description

The project has 3 primary components (1) build a fully separated bikeway to physically separate cyclists from heavy trucks, (2) rebuild and rechannelize two intersections (including constructing a fully protected crossing for cyclicsts at Horton), and (3) upgrade the S Hanford St signal to improve traffic operations and predictability for all modes. The scope of work (at 30% design) includes a 9.5 to 12-foot wide bikeway separated from the roadway by a concrete barrier, or landscaped buffer where space allows. At the intersections, work includes curb ramps and landings as well as curb radii and channelization improvements. A new roadway surface will eliminate cracked and rutted pavement and reduce ponding. The full corridor will eventually be upgraded to Heavy Haul concrete pavement, but a current rebuild will replace failed pavement sections with a new roadway surface through the intersections. At S Hanford St, this project proposes to relocate the existing railroad tracks further east, pending BNSF approval. Finally, adaptive signals and signal interconnect will be installed to maximize traffic throughput and minimize delays at peak and off-peak periods.

Existing Condition

East Marginal Way S (EMW) is one of Seattle's most intensively used freight corridors with direct access to 3 major seaports. Heavy trucks make up 1/3 of all traffic. It's also a well-used bicycle route due to its direct access between downtown Seattle, West Seattle, and regional destinations further south. 34,000 cyclists use this road each month with no physical barrier from heavy trucks. This unusual mix of travel modes creates a very uncomfortable facility for all users, and it has led to a number of injuries and fatalities. In particular, highly publicized bicycle/pedestrian fatalities in 2013 and 2017 have deterred many cyclists from using this facility. Outdated intersection designs and signal systems along the corridor also contribute to poor traffic operations and higher crash risk. Spikes in traffic volumes during seaport load and offload periods overwhelm the intersections and lead to aggressive driving and cycling behaviors. Existing railroad tracks at S Hanford St further complicate the crossing for bicyclists and truckers.

Project Benefits
