       Route 9W Bridge

This project involved the rehabilitation design of a 360 meter 14 continuous span bridge carrying state highway Route 9W over Cedar Pond Brook.

Savin performed detailed load rating analysis of the bridge using computerized structural modeling under various loading conditions to determine maximum stresses.
Rehabilitation design included new main girders, diaphragms, shear connections and a state of the art modular expansion joint system. Also included was design of temporary supports and girders such that construction could be staged allowing the bridge to remain open.

All design was performed in accordance with New York State Department of Transportation (NYSDOT) requirements and the American Association of State Highway and Transportation Officials (AASHTO) LRFD Bridge Design Specifications (SI Units).
