TriMet’s Aug. 23 service changes could reshape Portland commutes—what to plan for

TriMet is asking Portland-area riders to plan ahead for major bus and MAX changes starting Sunday, Aug. 23, 2026. The agency says the approved package will adjust service on 34 lines and eliminate two bus lines completely due to low ridership.

TriMet frames the package as part of a broader effort to reduce service while it works to close a significant long-term budget deficit. Many changes are centered on what it calls “network efficiency”—combining lines or reducing overlap where lines run near each other—while other routes are updated to maintain service in areas where people are riding.

MAX Green Line: shortened service between Clackamas Town Center and Gateway

The most noticeable change for many riders is to the MAX Green Line. TriMet says Green Line trains will run only between Clackamas Town Center and Gateway Transit Center.

For trips that need Downtown Portland service beyond that Green Line segment, TriMet directs riders to:

Use bus lines that run between most MAX Green Line stations and Downtown Portland, or
Transfer to MAX Blue or Red Line trains for trips between Gateway Transit Center and Downtown Portland.

34 lines affected: what “network efficiency” can mean in practice

TriMet says the August package includes route changes intended to improve how service is deployed across the system. In plain terms, that can translate to service being reshaped so that routes that run near each other don’t duplicate as much, while other routes are adjusted to maintain coverage where demand is stronger.

Local reporting also warned riders to expect real-trip impacts—potentially longer walks, an additional transfer, or an altered route for people who rely on TriMet for commuting, school, and medical appointments.

Why TriMet is making these cuts: a $158 million budget gap

TriMet says the August changes arrive amid financial pressure it says has reached a $158 million current budget gap effective July 1, 2026. TriMet also sets a goal of balancing its budget by July 2028.

The agency points to staffing reductions tied to a broader effort to resize TriMet. TriMet says overall staffing has dropped more than 500 positions since July 1, 2025. For 2026 reductions, TriMet says it will include about 400 positions eliminated and about 170 employees laid off as part of changes effective now through summer 2026.

TriMet also says service cuts are not limited to one date: it says it must reduce service levels by at least 10% by July 2028 to bring service in line with operating revenue.

What Portland riders should do before Aug. 23

With the changes still ahead, TriMet’s most practical step for riders is to verify route plans before the new schedules begin.

Check your line(s) on TriMet’s Aug. 2026 service-change page and compare it to your usual trip pattern.
If you rely on the Green Line, plan for the shortened routing and review TriMet’s transfer guidance for trips involving Downtown.
Build extra time—especially if your commute may require additional walking or a transfer.
For students and riders with accessibility needs, review how your stop-to-stop path changes, since network reshaping can affect where you connect.

What to watch after Aug. 23

TriMet also says the August package isn’t the end of the story. The agency states that further service cuts will be proposed this fall for next year.

If your household budgets around commuting costs and time—or if your regular route is a key link to work, school, or medical appointments—now is the time to check the line-by-line changes so Aug. 23 doesn’t create an unexpected detour.
