Bergen Arches in the Historical Context
Bergen Arches (a.k.a "Erie Cut") is a mile-long sunken railroad Right of Way in Jersey City, originally constructed between 1906 and 1910 and abandoned since the 1980s. Hidden for decades below protective barricades and fences, the rare ecological zone in the heart of the city is now flush with spontaneously seeded flora and fauna.
Current Conditions and Site Location
The Architecture of the Bergen Arches, a part of a larger effort by the local municipality and the NJ transit authority, engages access points and tunnel and bridge spaces as the key design framework for the new public space. Working with the local community, city agencies, and other collaborators, the project engages the unique anthropocenic geology, spatiality, and ecology of the Bergen Arches, to produce the new civic infrastructure that sensitively supports the existing historic structures and wildlife, as well as the new programmatic needs of the city.Access Points Framework
The access design for the Bergen Arches presents unique challenges and exceptional opportunities for thoughtfully designed infrastructure that enables equitable public access and engagement with the rare 1-mile sunken ecological corridor in the heart of the city.
Responding to the unique physical, logistical, regulatory, and environmental complexities of the site and its diverse and culturally rich neighborhood, the access design becomes, at an urban scale, a critical framework to coordinate the overall implementation of the project while providing the surrounding communities with inclusive access to nature and future programs, supporting the existing historic structures and wildlife. Considering factors including phasing and project timeline, grade separation, transit, and landing area availability, as well as the future tunnels and bridge programs, five access points are allocated across the length of the project.

Access Points Design - Preliminary Concept Diagram and View
![]()
At an architectural scale, the access points’ primary design concept is to integrate the experience of the vertical journey with various mid-air programs shared by the visitors and various flora and fauna of the Bergen Arches. The design prioritizes the use of
sustainable and wildlife-friendly materials.
Access Points Design- Selected Details
For instance, at Bevan X St.Pauls Avenues (shown at the top of the page), the access points provide a direct connection from and to the forthcoming St. Pauls Ave. Park and adjacent communities, including the residents of the nearby senior housing complex. The elevator on the southside accommodates accessible and safe routes for the users of the "Sensory Tunnel" program while the stair tower at the north side of the intersection, with carefully configured openings and material choices, doubles as a support structure for local and migratory birds congregating at Hackensack River with nesting spaces and feeding features and an observation tower for human visitors. The Palisade Avenue access point features a unique combination of structures, including a timber pedestrian bridge that traverses the Bergen Arches, offering an immersive journey through the tree canopy. This bridge, inspired by the historical tram flyover, not only connects visitors to the site but also provides a temporary pedestrian path during the planned Palisade Avenue bridge reconstruction. An elevator and stair on the RT. 139 side provide accessible routes and diverse vantage points, while also placing visitors in intimate proximity to the existing and new ecology of the Bergen Arches.
Tunnels & Bridges Adaptive Reuse
The historical tunnels and bridges, comprising one-third of the site and each with singular form, proportion, atmosphere, and micro-climate, offer distinctive spaces for community programs in the Bergen Arches, allowing the concentration of human-use in the existing structures preserving the ecological space outside and retaining historical narratives of the Bergen Arches.

Tunnels and Bridges - Program Allocation
Four program categories—Nature/Ecology, Knowledge/Education, Care/Rest, and Culture/Art—are proposed based on environmental and spatial characteristics of the tunnels and bridges, neighborhood programmatic contexts, and community partner inputs. The program combinations and configurations for each tunnel and bridge have been determined considering the proximity to potential partner institutions and organizations, as well as in relationship to possible future transit stops. Tunnels and bridges are activated in a phased, gradual, and distributed manner, coordinated with the construction of Access Points.
Tunnels and Bridges - program adaptations at selected tunnels

The Summit Avenue tunnel offers a main ecological educational facilit for the Bergen Arches that can partner with local schools and community organizations as part of an edible schoolyard or similar initiative, while providing an opportunity for year-round growing and an immersive indoor garden experience. The tunnel also includes nurser space for phyto-remediating plants, a seed library, and other ecological lab spaces for the care and study of the Bergen Arches’ ecology.

Palimpsest Wall and Sound Installation Area with Ballast Alcove at the western end of the Bevan Tunnel
The Bevan Tunnel, with its layered and exposed surface structures, presents a unique opportunity to showcase both the geological and constructed history of the Bergen Arches, as well as its industrial and infrastructural heritage. Fissures and crevices in the tunnel allow visitors to glimpse into the rock, inspiring a program that explores both the historical and multi-sensory experiences of the tunnel. Through specific installations and tactile moments, visitors are encouraged to pause and embark on a self-guided tour of the tunnel. A floating braille handrail and a suggestively marked pathway encourage movement through the space, which is designed to be inclusive for all visitors, potentially in partnership with St. Joseph’s School for the Blind and other local institutions.
Programs space vignettes for the Central Avenue Tunnel
The Central Avenue Tunnel functions as a multifunctional community hub, serving as the neighborhood's living room. As the longest tunnel with a uniquely immersive atmosphere, it is ideally suited to host a diverse range of programs, including projections, performances, and both formal and informal community gatherings such as readings, public assemblies, art displays, play, and communal food sharing. The tunnel also features a semi-outdoor library space, an archive with operable enclosures, and a contemplative water feature area with drinking ponds for small animals that connects to the natural ponding at the western end.
