Matrix conducted an in-depth preliminary engineering and feasibility study for Metro-North Commuter Railroad Company’s (Metro-North) evaluation of a several-mile long waterfront walkway located along the Hudson River. The project involved complex design considerations, including regulatory concerns associated with waterfront and in-water construction; safety concerns associated with pedestrian access immediately adjacent to an active railroad; complex construction logistics due to limited upland access to the site; incorporation of sea level rise resiliency into design elements; pedestrian access limitations that require pedestrian bridge crossings at frequent intervals; and accommodation of future track maintenance, including heavy machinery access along the proposed walkway.

Our professionals worked closely with both the Metro-North stakeholders (e.g. operations, maintenance, etc.) as well as the affected community. Matrix’s work included internal and public presentations to evaluate the feasibility of the project and to provide the owner with realistic schedule, cost, and regulatory expectations for their evaluation of the project.
