Putnam Bikeway over Metro-North Railroad, Stage 4

Putnam County, NY

HVEA designed this project that constructed a shared used path in the Town of Southeast, Putnam County. This project included one of the most difficult segments of the trail network as it crosses 4 tracks of the MNRR Harlem Line at the Brewster Rail Yard. It is part of the Comprehensive Plan for connecting New York City with Northern Dutchess County through a series of shared use paths. This portion of the SUP serves as a link between Westchester County’s North County Trailway and the planned Maybrook Bikeway.

HVEA designed a 500′ multi-span bridge that spans Metro-North’s Brewster Rail Yard, a maintenance road, and a siding track. The bridge will be founded on drilled shaft pier bents and MSE wall supported concrete stub abutments. Due to the required bridge clearance over the railroad, the bike path bridge approaches were required to be ramped up. This resulted in the need for extensive prefabricated retaining walls in order to stay within the ROW and to reduce the environmental impacts. This wall design included determining the wall layout/geometry that would meet the project requirements and provide details to allow for a contractor to select an economical wall system for this project. HVEA also provided construction support for this project and reviewed all of the retaining wall shop drawings to ensure compliance with the project requirements.

All of the construction is in the NYCDEP watershed. HVEA prepared a Stormwater Pollution Prevention Plan (SWPPP) and coordinated with the DEP to secure their approval. The project is funded with federal fund through the Federal Transportation Administration; FTA is functioning as lead agency for NEPA. HVEA also provided construction inspection services for this project and was responsible for the construction oversight including MPT implementation, contractor coordination and project recordkeeping and documentation.
