Downtown Phoenix Hub
The Downtown Phoenix Hub, also collectively known as Downtown Hub and City Hall, is a light rail hub on the A and B lines of the Valley Metro Rail system in Downtown Phoenix, Arizona. It is the western terminus of the A Line. The hub is located at the block formed by Central Avenue, 1st Avenue, Jefferson Street, and Washington Street. It comprises four one-way platforms: the northbound B Line platform on Central Avenue, the southbound B Line platform on 1st Avenue, the eastbound A Line platform on Jefferson Street, and the terminating westbound A Line platform on Washington Street. The hub serves riders as the transfer point between the A and B lines. A fifth platform at Washington/Central Avenue station just north of the hub is only used for early morning northbound trips on the B Line.
When opened in 2008, the two platforms at Jefferson/1st Avenue and Washington/Central Avenue were paired as the Downtown Phoenix stations of the light rail starter system. When the South Central Extension opened on June 7, 2025, Valley Metro introduced a new two-line system with the A Line and the B Line with an expanded and rebuilt hub. New platforms were constructed on Central Avenue, Jefferson Street, and Washington Street. The pre-existing platform at Jefferson/1st Avenue was integrated into the new hub, while the pre-existing Washington/Central Avenue platform on the northwestern side of that intersection was relegated to use only during early mornings.
The A Line runs from the Downtown Phoenix Hub to Gilbert Road/Main Street. The B Line runs from Metro Parkway to Baseline/Central Avenue.
