More About TPMC

The Seattle Department of Transportation (SDOT) and King County Metro (Metro) are partnering on multiple Transit-Plus Multimodal Corridor (TPMC) Projects to improve bus reliability, reduce transit travel times, and enhance pedestrian safety and access in Seattle. In addition to Route 40, we are also planning improvements to Route 48. Construction for routes 7 and 44 is currently underway.

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

TPMC projects aim to:

Make bus trips faster and more 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 Rapid Ride upgrades.

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

  • Make safety improvements for people walking and biking 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.
  • Utilize the City’s Race and Social Justice Initiative framework to evaluate and advance equitable outcomes.

Fulfill Levy to Move Seattle commitments

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