Falco peregrinus
The Maine Department of Transportation announced on February 14, 2012, that the bridge would be demolished starting that summer and be completed by the fall. The schedule was designed to accommodate the needs of two endangered species, the Peregrine falcon and the Shortnose sturgeon. Barges were placed in the Penobscot River onto which sections of the bridge were lowered. The concrete piers in the river are all that remains, and MDOT worked with the United States Coast Guard to design lights for them once the Bridge was removed to aid ships in the river. Later, MaineDOT announced that the low bid of $5.35 million by S&amp;R Corp. of Lowell, Massachusetts, was accepted.
