The scope for this Warren County Department of Public Works project includes the replacement of the existing culvert structure carrying Bay Road (County Route 7) over Halfway Creek (BIN 3360320) in the Town of Queensbury. The project limits encompass Bay Road from the intersection of Quaker Road (NYS Route 254) to the intersection with Glenwood Avenue. The existing structure, comprised of 3 corrugated metal pipes, is being replaced with a 50-foot-long single-span bridge structure with a width of approximately 90 feet to accommodate 5 traffic / turning lanes, an uncurbed median, and 5-foot-wide sidewalks. The replacement structure is being developed with provisions to improve hydraulics and provide a 75-year design life.
KC is responsible for performing hydraulic analyses and floodplain evaluations for the existing culvert and replacement alternatives, including hydraulic analyses for 50- and 100-year storm events and determination of 100-year Base Flood Elevations, in accordance with the New York State Department of Transportation (NYSDOT) Bridge Manual and New York State Department of Environmental Conservation (NYSDEC) Floodplain Management Criteria for State Projects, respectively. KC is also preparing the hydraulic report and developing scour and channel protection and floodplain mitigation measures to manage and control the movement of flood water.
