The B Line is a north-south light rail corridor in Phoenix, Arizona, forming part of the Valley Metro Rail network. Introduced on June 7, 2025, this addition transformed the system from a single route into a dual-line network. Stretching from Metro Parkway to Baseline/Central Avenue, the B Line encompasses 27 stations and significantly improves transit access within Phoenix’s central urban area.
Service description
Functioning as a newly established light rail route, the B Line extends from Baseline Road to the Downtown Phoenix Hub, then proceeds northward by merging with the pre-existing line up to Metro Parkway. To accommodate the expanded service demands, 17 new light rail vehicles will be incorporated into the fleet.
Beginning at Metro Parkway near the site of the former Metrocenter mall, the route travels eastward along an elevated viaduct above Interstate 17, runs parallel to Mountain View Road, and then heads south along 25th Street past the Rose Mofford Sports Complex. It continues southward to Dunlap Avenue, briefly turns east, and then moves south on 19th Avenue for approximately four miles. After three stops on 19th Avenue, it veers east onto Camelback Road for 2.5 miles before turning south onto Central Avenue entering Downtown Phoenix. Between Roosevelt and Lincoln Streets, the line operates on separate one-way tracks before converging again at Hadley Street and continuing south beneath Interstate 17 and over the Salt River bridge to its terminus at Baseline/Central Avenue station.

History
The northern segment of the B Line beyond Downtown Phoenix was originally constructed as part of the Valley Metro Rail network, debuting service to the Montebello/19th Avenue station in 2006. Later, the Northwest Extension Phases I and II, completed in 2016 and 2024 respectively, pushed the line’s northern endpoint further to Metro Parkway station.
The line was extended southward from Downtown Phoenix along Central Avenue reaching Baseline Road, incorporating eight additional stations and two park-and-ride locations into the Valley Metro Rail system. This expansion also featured a newly established central downtown station, which improved operational efficiency by allowing trains to perform short turn maneuvers during busy periods and special events.
Following environmental clearance from the Federal Transit Administration (FTA) in January 2017, the project moved forward into the design phase. Initial proposals to reduce Central Avenue’s general traffic lanes from four to two to accommodate rail tracks encountered public resistance. Nonetheless, the city council approved the plan, despite a subsequent unsuccessful ballot initiative intended to stop funding for Valley Metro Rail. Construction commenced in 2019 and was completed in 2025, with the extension officially opening on June 7.
