The Project: Originally built in the 1930s, the Eliot Road Overpass in Kittery, Maine is being replaced by a single span, precast/prestressed concrete bridge using the New England Extreme Tee or NEXT Beam. J.P Carrara & Sons in Middlebury, Vermont supplied the beams for the project, cast in forms fabricated by Hamilton Form Company. The Solution: The formwork for the NEXT Beam resembles a typical double tee, but is designed for self-stressing up to 2200 kips. In addition to form skin and stiffeners, compression bars help carry the prestress load. Thick jacking plates evenly distribute the load. Magnetic side rails provide flexibility to cast different beam widths in the same form. The Result: The self-stressing formwork was set up and Carrara was casting within days of delivery. The wide bridge sections are more efficient than typical box beam or voided slab bridges. NEXT Beams butt together providing an instant work platform and act as formwork for the deck pour. The 10,000 cars that use the Elliot Road Overpass every day will soon benefit from a new, safer bridge built with NEXT Beams provided by J.P. Carrara & Sons.
