The Highway and Bridge Engineering Section is responsible for planning, programming, pursuing funding, and administering the design and construction of all County highway, bridge, and culvert capital improvement projects. This Section reviews and coordinates the installation and replacement of traffic features (signs, pavement markings, and traffic signals) for City of Rochester street projects. This Section is also responsible for engineering, inspecting, and prioritizing an annual preventive maintenance program for approximately 120 bridges owned by the County, including the Irondequoit Bay Outlet Bridge (IBOB), approximately 60 bridges co-maintained with other agencies such as New York State DOT and New York State Thruway Authority, and approximately 350 major culverts. Guide rail and retaining wall design, installation, inspection, and repair are also the responsibility of this Section.
The O'Rorke Bridge Operations Section operates and maintains the Colonel Patrick O’Rorke Memorial Drawbridge on behalf on New York State DOT in order to move people and goods safely and efficiently over the Genesee River between the City of Rochester and Town of Irondequoit. The bridge operates 24 hours per day, seven days per week, from April 1 through December 15 each year, and with at least 12 hours advance notice at all other times . It is estimated that the bridge is lifted 325 times per year. The lower part of the Genesee River is classified by the U. S. Coast Guard as a navigational channel and federal law requires that the waterway be unobstructed (CFR 117.785).
