context_page_description: The Loop Service is a streetcar circle route in Portland, Oregon, United States, that is part of the Portland Streetcar system. Operated by Portland Streetcar, Inc. and TriMet, it consists of two distinct services: the 6.1-mile A Loop, which runs clockwise, and the 6.6-mile B Loop, which runs counterclockwise. Each service travels a loop between both sides of the Willamette River, crossing it on the Broadway Bridge in the north and Tilikum Crossing in the south. The route connects Portland's downtown, Pearl District, Lloyd District, Central Eastside, and South Waterfront. It serves the city's various landmarks and institutions, including the Rose Quarter, the Oregon Convention Center, the Oregon Museum of Science and Industry, Oregon Health & Science University, and Portland State University.
  Portland city officials first proposed building an eastside streetcar line in 1997, at the same time the city council authorized the construction of Portland's first modern streetcar line on the west side. After several years of planning, the city council approved the Eastside Loop extension in 2008 and held the line's groundbreaking the following year.

Operated by Portland Streetcar, Inc. and TriMet, it consists of two distinct 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. Each service travels a loop between both sides of the Willamette River, crossing it on the Broadway Bridge in the north and Tilikum Crossing in the south. The route connects Portland's downtown, Pearl District, Lloyd District, Central Eastside, and South Waterfront. It serves the city's 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).
  Portland city officials first proposed building an eastside streetcar line in 1997, at the same time the city council authorized the construction of Portland's first modern streetcar line on the west side. After several years of planning, the city council approved the Eastside Loop extension in 2008 and held the line's groundbreaking the following year. The extension's first 3.3 miles (5.3 km) opened between the Broadway Bridge and OMSI on September 22, 2012. It was inaugurated by the Central Loop Line (CL Line) service, which ran an additional 1.1 miles (1.8 km) on the west side alongside the NS Line on 10th and 11th avenues. The CL Line was re-branded to its current name in 2015 during the opening of Tilikum Crossing, which completed the streetcar loop with a southerly river crossing extension from OMSI to the South Waterfront.
