The system's second line opened in 2012 and extended service across the Willamette River to the Lloyd District and the Central Eastside. The federal share of funding for this $148-million project, a extension and fleet expansion, was approved in April 2009, and construction began in August 2009. Originally named the Central Loop Line, or CL Line, it was renamed the A Loop (clockwise) and B Loop (counterclockwise) in 2015, when it was extended from the eastside across the Tilikum Crossing bridge and also along the NS Line from South Waterfront to Portland State University. See Portland Streetcar (Eastside line) and Loop Service (Portland Streetcar) for more detail.
