Replacement of the East Johnson Avenue Bridge, Cheshire CT

Cardinal Engineering provided design services, construction inspection and contract administration for the replacement of the East Johnson Avenue Bridge. The project was funded under the Federal Local Bridge Program.

The original bridge was a 94 -foot, two-span prestessed concrete deck with a concrete-filled steel pipe pile. The bridge was hydraulically-inadequate and scour critical. During preliminary engineering, the center pier was found to be unstable, therefore Cardinal determined that a total replacement was the best option for the structure. The replacement alternative was a 104-foot single span bridge with integral abutments and prestressed concrete box beams. The advantages of the chosen design included a 75-year design life requiring less maintenance, simple construction methods, jointless bridge, elimination of the center pier and hydraulically-adequate opening.
