The Loop Service is a circular Portland Streetcar line that connects downtown Portland, Oregon, to the Central Eastside via two crossings of the Willamette River: the Broadway Bridge to the north and the Tilikum Crossing to the south. It is composed of two services: the A Loop, running clockwise, and the B Loop, running counterclockwise. The line was known as the Central Loop Line (CL Line) from its opening in 2012 until the opening of Tilikum Crossing bridge in 2015.
