​Cadre has extensive experience detailing widenings for a variety of structures. We have detailed widenings for concrete slabs, box girders, prestressed concrete girders and deck overhangs. These projects are located throughout the state and were designed for numerous agencies. Selected projects are:

This widening also included retrofit of existing structures. Cadre detailed plans for Santa Clara County following Caltrans standards.
