Prospect Hill Road Bridge

MTA Metro-North Railroad secured the Halmar-WSP Design-Build team to provide expedited design and construction services for the $9.45M replacement of the Prospect Hill Bridge located on the Harlem Line over the Brewster Yard and just south of the Southeast train station. During the demolition of the existing bridge and the reconstruction of the new structure, the following needs were considered:

• Minimal disruption of the operations of the Brewster Yard, Brewster Yard Access Roadway and Brewster Yard Employee Parking Area, and
• Final design to account for future expansion of the Brewster Yard Tracks

SJH provided design and development of deck/approach slab reinforcement, parapet/guiderail transition/ornamental fence details and performed load ratings for the proposed superstructure. In addition, SJH provided load rating calculations for the structure and reviewed several steel framing shop drawings submitted by the contractor.
