Creative design solutions to improve overall transit capacity at South Ferry Tunnel
Dealing with this dense underground site required the team to come up with creative design solutions to not only fit the tunnel and station but also enhance operations to improve passenger transit capacity. We designed an underground, reinforced concrete structural box to house the new 900-foot approach tunnel and 600-foot long station with train platforms.
To limit the extensive excavation that was required, the new box was positioned beneath an existing subway tunnel so the floor could be integrated with the roof of the new structure. This saved crucial space and money for rock excavation and construction schedule duration
The new tunnel/station box also allowed the alignment of the track to be straightened, a significant improvement over the existing loop track with a curved movable platform in the old station. This allows for more space for trains and people, and the train speed to improve, all increasing capacity within the system.
