March service improvements include new service and route adjustments to better connect riders with employment, education, community services

New bus service and better access to the region’s employment corridors are ahead as TriMet rolls out improvements for spring 2018. We’re adding three new bus lines, adjusting three routes and adding service on some other lines to help people get where they need to go while improving the efficiency and reliability of TriMet’s bus service. These changes reflect our commitment to a 10-year expansion of service that aligns with the region’s projected growth and efforts to ease traffic congestion.

TriMet’s spring service begins on March 4. Plan ahead using the Trip Planner available at trimet.org.

Improving the ride

As part of our commitment to better bus service, we’re also improving the ride. Since 2012, TriMet has added 512 new buses, reducing the average age of our fleet to about seven years. Newer buses improve reliability, use cleaner-burning fuel technologies that reduce carbon emissions and make for a smoother, more enjoyable ride.
