High Line Moynihan Connector

overview

Linking the Moynihan Train Hall with the High Line at 10th Avenue, a new pedestrian pathway provides safer and more enjoyable access to the West Side, building upon New York City’s vision to improve the way its neighborhoods connect.

We provided structural and connection engineering design to SOM for the elevated pathway, which comprises two distinct bridges that span over Midtown’s busy avenues. The Woodlands Bridge is a 375-foot-long path extending eastward from the existing High Line along 30th Street, enveloping pedestrians with deep soil beds that provide a lush, scenic experience. At the eastern end of the Woodlands Bridge, the path turns north over Dyer Avenue via the Timber Bridge to connect to a new, elevated public space at Manhattan West which continues to Moynihan Train Hall.

highlights

• The east-west Woodlands Bridge is supported by a combination of weathering steel framing and precast concrete, which facilitated a rapid construction schedule.
• The Timber Bridge consists of a three-span, 250-foot-long Warren truss structure made of sustainably sourced glued laminated timbers, each spanning from 80 to 90 feet. It is supported on two columns positioned to minimize interruptions to traffic during construction and allow for future roadway changes.
• Although the bridge visually interfaces with Manhattan West, the northern span cantilevers 78 feet to avoid the need for an additional support column at the busy Lincoln Tunnel entrance below.
