Wyman & Simpson constructed the world's first multi-span hybrid composite beam bridge over the Back River in Boothbay, Maine. Bridge piers were built on site and 62 HCB beams – made of glass fiber, foam and steel – were trucked in from a manufacturing facility in Brunswick, Maine – and placed by W&S crews. Project included construction of pipe pile supported piers, rock anchor installation, composite beam erection, concrete bridge deck, bridge supported power, telephone, cable and town owned water main, two precast concrete retaining walls, 2,100 feet of roadway, boat ramp and parking lot construction. The project was completed under budget and ahead of schedule. It was dedicated in early 2011. The bridge – and two other composite bridges built by Wyman & Simpson – were featured in Maine Trails magazine. Read more.
