A and B Loop
The A and B Loop is a streetcar circle route of the Portland Streetcar system in Portland, Oregon, United States. Operated by Portland Streetcar, Inc. and TriMet, it consists of two services within the Central City that travel a loop between the east and west sides of the Willamette River by crossing the Broadway Bridge in the north and Tilikum Crossing in the south: the 6.1-mile (9.8 km) A Loop, which runs clockwise, and the 6.6-mile (10.6 km) B Loop, which runs counterclockwise. The services connect Portland's downtown, Pearl District, Lloyd District, Central Eastside, and South Waterfront, and serve various landmarks and institutions, including the Rose Quarter, the Oregon Convention Center, the Oregon Museum of Science and Industry (OMSI), Oregon Health & Science University (OHSU), and Portland State University (PSU). Riders can transfer to the regional MAX Light Rail system at several points along the route.

Portland city officials considered an eastside streetcar extension upon authorizing the Central City Streetcar project on the west side in 1997. After several years of planning, the Portland Streetcar Loop Project was approved and held its groundbreaking in 2009. Its first 3.3 miles (5.3 km) opened between the Broadway Bridge and OMSI on September 22, 2012, inaugurated by the Central Loop Line (CL Line) service, which ran additionally on the westside along 10th and 11th avenues. The opening of Tilikum Crossing in 2015 extended the eastside streetcar from OMSI to the South Waterfront; this completed the loop and rebranded the CL Line to A and B Loop.
