More About TPMC

Transit-Plus Multimodal Corridor (TPMC) Projects are designed to improve bus reliability, reduce bus travel times, foster business and freight activity, and enhance pedestrian safety and access in Seattle. In addition to Route 40, improvements are being planned for Route 48. Construction for routes 7 and 44 is currently happening.

Travelers board a Route 40 bus.

Route 40 buses help get you where you need to go.

TPMC projects aim to:

Make bus trips more efficient and reliable, now and in the future

  • Reduce bus travel times, especially during peak traffic hours by minimizing traffic-related delays.
  • Keep buses moving reliably, especially during peak traffic hours and when major disruptions occur.
  • Implement improvements that protect buses from increased levels of congestion and support planned RapidRide upgrades.

Make it safer and easier to get to and on the bus

  • Make safety improvements for people walking, rolling (using a wheelchair or other mobility device), biking, or scooting to the bus.
  • Improve accessibility for all bus riders, regardless of age or ability.
  • Maintain and repair streets, sidewalks, and bus stops to support bus access.

Advance program objectives in a way that responds to community needs and priorities

  • Work with the community and stakeholders to evaluate investments that align with the program objectives.
  • Use the City’s Race and Social Justice Initiative and Transportation Equity Framework to evaluate and advance equitable outcomes.

Fulfill Levy to Move Seattle commitments

  • Deliver on the 2018 Levy Assessment commitments.
  • Coordinate with King County Metro and other SDOT programs to ensure efficient delivery of projects while managing risks.

Bus lane success stories

Throughout Seattle, implementing bus lanes and transit priority at intersections has a good impact on reducing travel times for buses. We’ve made improvements to the Route 7 and Route 44 corridors, which overlap with several other Metro, Sound Transit, and Community Transit routes. Based on preliminary data on existing business access and transit (BAT) lanes, buses have experienced faster travel times, resulting in a more efficient transit system.

Some successes so far include:

  • NE 45th St BAT lane: 13-14% reduction in transit travel time
  • 15th Ave NE BAT lane: 4-9% reduction in transit travel time
  • Rainier Ave BAT lane: 2-6% reduction in transit travel time
