Description

The construction of this bridge is unique in Maine as it consists of two bridges, one built on top of the other to accommodate a change in grade of the highway. The first bridge, designed in 1919, is a through deck reinforced concrete structure. The second bridge, designed in 1932, is a reinforced concrete T-beam structure with open spandrel arches erected on the deck of the 1919 bridge. The 1932 bridge forms a second tier and suggests the appearance of a Roman aqueduct. The unknown designer(s) found a solution to adapt an existing bridge to meet the requirements for raising the grade of a major highway while creating one of the most unusual engineering monuments in the state.
