Rehabilitation of the Main Street Bridge over the Bronx River Parkway
HVEA is providing preliminary and detailed design, construction support and inspection services for the Rehabilitation of the Main Street Bridge over the Bronx River Parkway and and Bronx River in White Plains, NY. The original structure was built in 1922 and consists of two spans: 63′ long by 100′ wide sand 60′ long by 72′ wide. This project will rehabilitate and extend the service life of the existing structure by removing the existing wearing surface and saturated fill material, repairing damage done by intruding water, waterproofing the arches, placing new fill, upgrading drainage, restoring the wearing surface and repairing the concrete and stone masonry. This project will also raise the existing parapet walls to a height of 42″ in order to comply with ADA/PROWAG requirements. As the bridge is in the Bronx River Reservation and is National Register Eligible, there is extensive coordination with SHPO to meet Section 106 and 4(f) requirements.
This bridge is a major entrance point to the City of White Plains, with upwards of 44,000 vehicles per day. M&PT is a critical component of the project and will require a detailed phasing plan during construction to both maintain traffic and perform the work efficiently.
