Grimshaw, in partnership with Gruen Associates, led the design for the Los Angeles Union Station Master Plan. The scheme preserves the celebrated qualities of the historic station and its surrounding 17 hectares while addressing the urgent needs of the future.

The master plan includes a new passenger concourse which will provide a large-scale civic space for passengers and related support functions and amenities. Additionally, a new bus facility will consolidate local and regional bus functions, bringing passengers in closer proximity to additional modes of transport.

Other enhancements include improved wayfinding and a more efficient layout with flexibility for future growth that might include the placement of high speed rail service at or near Union Station.

The master plan enhances passenger and visitor experience by forging new connections to nearby destinations and inspire a mix of uses that reflects the shifting demographics of users. The increased level of activity combined with renewed access, easier navigation and open space improvements encourages visitors to linger, fostering the idea that Union Station is a full-time destination in Los Angeles.
