Palisades Road Bridge Replacement
Warren County’s Department of Public Works with NYSDOT contracted Azar Design Co to deliver structural design services for the replacement of Palisades Road Bridge (County Route 26) over Brant Lake Inlet. The abutment substructure units that supported the previously existing bridge superstructure were severely deteriorated, resulting in low element condition ratings and reduced General Recommendation and Sufficiency Ratings for the bridge.
Azar provided survey & mapping, environmental, preliminary and final design, bidding, construction assistance and construction inspection.
A complete hydraulic analysis was required. The replacement structure remains on a similar horizontal alignment, while minimal vertical alignment adjustments address the hydraulic opening and new structure type. The bridge cross-section increased width to accommodate NYSDOT, AASHTO, and County bridge standards.
Azar’s team delivered comprehensive designs for adequate drainage, utilities, guide rail, and adjacent landscaping improvements. New signage and pavement markings for the entire project corridor meet current MUTCD standards.
Changes to the roadway profile required replacement of an existing retaining wall protecting the privately owned lakefront beach adjacent to the reconstructed roadway. To minimize the impact on the beach, our engineers designed a new prefabricated wall system utilizing a Redi-Rock product, along with updated stairs for safe access. The beach owner was frequently engaged during construction to ensure their satisfaction with the finished wall.
This project was honored by APWA’s Capital Branch as the 2022 Disaster or Emergency Construction/Repair Project of the Year.
