Pioneer Road Bridge over Canaseraga Creek

This locally administered federal aid (LAFA) project included the replacement of an existing three-span, single lane truss, 100-foot bridge that carries Pioneer Road over Canaseraga Creek. Pioneer Road is a dirt road that sees very little traffic except when an adjacent NYSDOT bridge regularly closes due to flooding. The existing alignment is poor with inadequate sight distance and a tight curve adjacent to the bridge. The proposed bridge was built on an improved alignment in anticipation of future plans to pave the entire road and increase its functional classification. The profile was also raised to improve the hydraulic opening under the bridge for this volatile creek. The bottom elevation of the superstructure was designed to be above the elevation of the creek’s flood control levees, thus ensuring the bridge will not act as a constriction. The proposed structure is a single-span, prestressed concrete box-beam structure, approximately 115 feet long. Integral abutments were used with deep pile foundations. Since the project is in a rural location, ROW donation was used for the acquisition of property. C&S was responsible for phase I-VI design and construction inspection. Specific tasks included cultural resource assessment, performing all ROW acquisition tasks, significant hydraulic analysis, and final highway and bridge design. This project received a 2011 ACEC New York Gold Award for Engineering Excellence.
