MAX Red Line Extension

TriMet is extending its MAX Red Line west to serve 10 more stations between Beaverton and Hillsboro. On the east side, second tracks near Gateway Transit Center and at Portland International Airport will remove significant constraints and will improve scheduling and reliability for the entire MAX system. In addition to light rail improvements at Gateway, the project encompasses a new multi-use path that will connect the transit center to an existing park just north of the I-84 crossing; the path will provide a new connection for pedestrians, cyclists, and emergency vehicles.

Parametrix provided project management, track design, civil and stormwater design, structural design, and environmental leadership throughout the design phase. At the Gateway location, we designed a new structure to cross over I-84 and the Union Pacific Railroad and under a major arterial. Parametrix engineers developed extensive special track work and overhead contact system connections that will tie into the existing system.

At the airport location, engineers worked with TriMet and the Port of Portland to consider the airport and the needs of the transit system and its customers, landing on design and construction of a new station platform at the terminal. The team designed new special track work and systems layouts for the proposed terminus.

Project staging and phasing has required extensive coordination with TriMet and the GC/CM. Parametrix staff are continuing to support TriMet through construction.
