LA Metro Regional Connector @ 2nd/Broadway – Historic Broadway Station
Project Overview
The Regional Connector in downtown Los Angeles is a 1.9-mile light rail system connecting the Metro Gold Line to the 7th Street Metro Station. Passengers will be able to travel between Azusa and Long Beach and between East Los Angeles and Santa Monica on the same train. The project includes three underground stations: 1st/Central, 2nd/Broadway, and 2nd/Hope.
AVA optimized all three station designs by simplifying ancillary-area layouts and improving horizontal and vertical relationships between equipment rooms. These changes reduced station footprints at all levels, simplified construction, and reduced construction costs.
At the direction of the mechanical engineers, station ventilation fans and associated rooms and ducts were removed from the designs, and the emergency fans were configured to perform these functions.
Historic Broadway Station
AVA relocated the auxiliary power rooms from the preliminary engineering auxiliary level to the concourse level. Ancillary rooms within the train box were rearranged to maximize free area.
The ancillary block was consolidated into the same footprint on both levels to simplify construction and reduce costs. A common equipment shaft within this footprint serves both levels.
AVA reduced the ancillary level footprint by 65%, the concourse level footprint by 8%, and the platform level footprint by 6% compared with the preliminary engineering layouts.
The station design integrates with historic downtown Los Angeles and the planned streetcar system on Broadway Street.
