"Bridge in a Backpack" - Auburn, Maine

Owner: MaineDOT

Contract Amount: $764,164

Completed: 2010

In 2010, Wyman & Simpson had three different composite bridge projects underway. This "bridge in a backpack" project spanning the Royal River in Auburn was challenging because it required construction of a headwall in steeper conditions than previous bridges built from this same composite design. The project also included removal of the existing single-span bridge, sheet pile cofferdams, utility coordination, h-pile installation, concrete abutments, four precast concrete retaining walls and approach earthwork.

Knickerbocker Bridge - Boothbay, Maine

Owner: MaineDOT

Contract Amount: $3.84 million

Completed: 2011

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.

Boom Birch Bridge - Old Town, Maine

Owner: MaineDOT

Contract Amount: $1.35 million

Completed: 2007

This project, undertaken in 2007, was a fast-track demonstration bridge replacement for MaineDOT under the Federal Highway Administration's Highways for Life program. Because of the advanced deterioration of the existing bridge, the contract required the bridge to be completed in less than seven weeks. The bridge was constructed entirely of precast concrete components (shown here are crews placing one of the precast bridge abutments).
