A and B Loop
streetcar circle route in Portland, Oregon, U.S.

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 is made up of two separate services: 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 route travels 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 A and B Loop connects Portland's downtown, Pearl District, Lloyd District, Central Eastside, and South Waterfront. It serves 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 Frequent Express (FX) and MAX Light Rail from several stations along the route.
Portland city officials considered an eastside streetcar line upon authorizing the Central City Streetcar on the west side in 1997. After several years of planning, the Portland Streetcar Loop Project was approved and held its groundbreaking in 2009. The first 3.3 miles (5.3 km) opened between the Broadway Bridge and OMSI on September 22, 2012.

Why this record matters
The subject matters to the general reference register because the source frames it as streetcar circle route in Portland, Oregon, U.S. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 23, 2026. The linked authority identifier is Q16900249. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1997, 2009 and 2012.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
