Analysis Bergen Arches Feasibility Study 

The Bergen Arches is a 60 feet wide, 40 to 70 feet deep, three-quarter-mile long trenched  and abandoned railway corridor with numerous overhead bridges and tunnels in Jersey  City. Excavated out of blue rock, it was originally constructed by the Erie Railroad at the  turn of the 20th century to connect its main lines west of Jersey City to the Hudson  Riverfront directly across from Manhattan. The Department of Infrastructure of the City of  Jersey City commissioned the Bergen Arches Feasibility Study and solicited an investigation  of the Bergen Arches as a greenway and transit corridor. The completed study represents  a tangible and validating step out of many towards realizing a one-of-a-kind greenway and  transit corridor through the city. When realized, the Bergen Arches can serve the city in  many ways, including providing ways to engage nature as an urban forest, providing  recreational opportunities as a park, enhancing mobility as a transit way, and connecting  people and neighborhoods as a community resource. 

As prime consultant, the landscape architect worked with a team of civil, structural, geotech  and transit engineers, lighting designers, and architects to lead the study and develop an  overall framework plan which accommodates a transitway, offers various programming  opportunities and amenities along the greenway, and provides safe access for the public.  Over the course of the project, the project team also coordinated with the city to host three  public open houses to provide a forum for community visioning, dialogue, and discussion.  The feasibility study included an existing conditions assessment documenting major  ecological and physiographic conditions along the corridor, a preliminary structural  assessment of the tunnel and bridges, as well as a review of the local urban context.  

The framework plan articulates a broad vision and a set of guiding principles for the  greenway and establishes a roadmap for future planning and design phases, including its  eventual integration into a larger city and regional greenway and transit network. The plan  also included a preliminary maintenance assessment, phasing strategies, regulatory  requirements, and a grant and funding strategy. The greenway design and alignment,  including the tunneled portions, are responsive to the unique site conditions found in the  Bergen Arches.  

Preserving the innate natural and ecological qualities of the Bergen Arches overwhelmingly  favored by the local community while adapting it for use as a public greenway and transit  corridor is a unique challenge for the project. The project outlines an immediate and longer  term vision of preservation, restoration, and phytoremediation strategies that balance the  desire for nature preservation, the need for safe ground remediation in a contaminated  environment, and the need to restore degraded ecological environments that have been  overrun by invasive flora with ecologically valuable flora that can promote a healthier and  more biodiverse greenway and transit corridor for the future.
