The
MAX Orange Line, also known as the
Portland–Milwaukie Light Rail Project, is a
light rail line in the
Metropolitan Area Express light rail system in
Portland, Oregon. The $1.49 billion project is the second part of a two-phase transportation plan known as the South Corridor Project, bringing light rail service to
Clackamas County. Starting in
downtown Portland and following the
Portland Transit Mall, the Orange Line runs between
Union Station and
Milwaukie, terminating at Park Avenue, in unincorporated Clackamas County just outside Milwaukie proper. The first construction work, related to the new
Tilikum Crossing over the
Willamette River began on June 30, 2011, and the line opened for service on September 12, 2015.
