Replacement of the Hillside Avenue Bridge over the Mamaroneck River

Village of Mamaroneck, NY

A Bridge NY funded project, HVEA is providing the preliminary and final design services for the Replacement of the Hillside Avenue Bridge over the Mamaroneck River. This replacement project follows the procedures for Locally Administered Federal Aid Projects and has an accelerated schedule requiring design and right-of-way acquisition to be completed within 18 months to meet the Bridge NY timing requirements. This project involves the oversight of not only the Village of Mamaroneck, but also the Towns of Mamaroneck and Rye via intermunicipal agreement. HVEA is finalizing the design approval document and advance detail plans. Because the bridge is eligible for the National Register of Historic Places, HVEA prepared a Section 106 Finding Document and Memorandum of Agreement for DOT, SHPO and FHWA approval. This project also involves the realignment and reconstruction of the west approach to the bridge, including new curbing, 5′ wide sidewalks and a curb ramp. All sidewalks and curb ramps are designed to meet ADA and PROWAG standards. Services include:  topographic & boundary survey, bridge and roadway design, subsurface investigation and design, hydraulic analysis, scour protection, utility coordination, multi-municipal coordination, US Army Corps of Engineers coordination, SHPO coordination, NEPA/SEQR determinations, DEC/ACOE permitting, ROW incidentals and acquisition, EDPL public hearing, public participation and construction support services.
