TriMet riders traveling between the Rose Quarter and Expo Center will face a week of service disruptions as the agency implements track improvements. Shuttle buses are replacing MAX Yellow Line service through the end of the week to accommodate the construction.
Why it matters
The closures are part of a targeted effort to improve track resilience against extreme summer heat across the transit system. By hardening these sections now, TriMet aims to prevent future heat-related speed restrictions or service failures during the next hot season.
TriMet is upgrading three track locations to better withstand extreme summer heat. Riders should plan for 30 minutes of extra travel time, with shuttle buses running every 15 minutes.
The players
TriMet
The regional transit agency responsible for operating bus and light rail services in the Portland metro area.
The details
Crews are working at three specific sites to complete track upgrades meant to keep rails stable during high temperatures. During the project, TriMet has suspended regular MAX Yellow Line trains between the Rose Quarter and Expo Center. Shuttle buses are currently providing bridge service for commuters who rely on this line to travel north or south of the river.
Timeline
October 26, 2026: Partial closure of MAX Yellow Line begins.
November 1, 2026: Full MAX Yellow Line service resumes.
Beyond the Bridges
This work aligns the city's light rail infrastructure with the increasing frequency of extreme heat events documented by the National Weather Service's Excessive Heat Warning criteria. It marks a preventative step to ensure transit reliability remains consistent even as regional temperature records are tested.
If you rely on the Yellow Line to commute or reach the Expo Center, build an extra 30 minutes into your trip through the end of the week. Look for the shuttle bus stop signs at each station between Rose Quarter and Expo Center for your replacement ride.
The takeaway
Anticipate travel delays on the Yellow Line through the end of the week as maintenance crews prepare the tracks for future summer heat. Riders should check current service alerts on the transit portal before heading out each morning until regular service resumes on November 1.
What happens next
Full MAX Yellow Line service is scheduled to resume on November 1, 2026.
