Project Description

CP Rail Bridge over Nott Street

City of Schenectady, Schenectady County, New York

Creighton Manning provided preliminary and final engineering services for the bridge replacement of the Canadian Pacific Railway (CPR) Bridge over Nott Street in the City of Schenectady. Additional services included topographic survey and mapping; concept plan development; coordination with CPR and the City of Schenectady; soil borings and geotechnical analysis; and constructability assessment. As the City has changed and grown over the past century the area around the Nott Street bridge has become more constrained, impacting the flow of people and goods under the bridge and making typical bridge construction nearly impossible. Overheard utilities at all four corners of the bridge, an adjacent building, two adjacent billboards, and being parallel to a major commuter roadway eliminated the feasibility of multiple cranes, sliding systems, or adjacent construction. Operational constraints during construction included minimizing impact to railroad operations and minimizing impact to vehicular and pedestrian traffic on both Nott Street and Erie Boulevard. The new 120 ft. span is long enough to accommodate an additional lane of traffic required for projected traffic demands at the new roundabout. Creighton Manning was also responsible for obtaining permits from the City and NYSDOT for road closures and detours.

“Excellent timing on completing construction to open Nott St. Thank you for your work on this project. Things went smoothly due to your diligent management. Well Done!”
John F. Unsworth, P.Eng., Deputy Chief Engineer Structures, CP Structures
