KCI provided construction engineering services for the High Line – Moynihan Connector, a signature infrastructure project in New York City that creates a direct connection between the High Line, Moynihan Train Hall, and the Manhattan West district.
The project introduced a 600-foot-long elevated pedestrian pathway composed of two distinct bridge structures, forming a continuous, fully accessible route between major transit hubs, public open space, and mixed-use developments in Midtown West. Constructed within a dense urban corridor above active roadways and rail infrastructure, the connector enhances pedestrian circulation in one of the busiest areas of Manhattan while minimizing conflicts with vehicular traffic below.
KCI supported construction of the connector’s two primary structural elements: a north–south timber truss bridge spanning Dyer Avenue and an east–west landscaped steel bridge extending from the High Line. Both structures required detailed planning of erection sequencing, temporary stability systems, and load transfer mechanisms to safely advance construction over live traffic. The constrained site and limited staging areas demanded precise coordination of crane operations, material deliveries, and structural installation in close proximity to adjacent infrastructure and ongoing urban activity.
KCI’s role focused on developing comprehensive erection sequencing strategies and designing temporary works to maintain structural integrity throughout all phases of construction. This included stabilization of partially erected truss systems, coordination of load paths during critical picks, and engineering solutions to accommodate tight tolerances and restricted access conditions. Continuous collaboration with the contractor and design team allowed the project to adapt to field conditions while maintaining schedule and safety requirements.
The design and construction process emphasized constructability and seamless integration with the surrounding built environment. Close coordination among stakeholders ensured alignment with the architectural and landscape vision of the High Line, as well as functional connectivity to Moynihan Train Hall and adjacent public plazas.
Completed in 2023, the connector delivers a grade-separated pedestrian link between Penn Station, Manhattan West, and the High Line. The new pathway significantly improves accessibility, enhances pedestrian safety, and strengthens connectivity across Midtown West, supporting increased foot traffic and enriching the public realm in this rapidly evolving part of the city.
