Construction is expected to run from summer 2011 to spring 2015.


The Portland-Milwaukie Light Rail Project will travel 7.3 miles, connecting Portland State University in downtown Portland, inner Southeast Portland, Milwaukie and north Clackamas County. MAX service on the alignment is scheduled to begin in 2015. By 2030, when this future light rail line will carry up to 27,400 daily rides, there will be approximately 22,000 households and 85,000 employees within walking distance of Portland-Milwaukie light rail stations.

Local jurisdictions approved the light rail's route, terminus and station locations by adopting a Locally Preferred Alternative in July 2008. TriMet will carry the project through construction, working closely with property owners, businesses and neighborhoods. Visit TriMet's Portland-Milwaukie site for the latest on the new Willamette River bridge, project updates and opportunities to participate.

What about river users?

Metro and its partners are investigating the possible effects of the Portland-Milwaukie Light Rail Project Willamette River crossing on river users. A key tool in this effort is the river survey provided by the National Oceanic Atmospheric Administration.
