Veterans Memorial Bridge
Bath, ME
Project Description
The existing Veterans Memorial Bridge was built in 1954 to connect Portland's West End to South Portland over the Fore River and carries over 22,000 vehicles per day. The replacement bridge will be built on a new alignment in the vicinity of the existing structure. Maine DOT utilized a "best value" scoring process for its selection of the design-build team that took into account the technical value of innovations and features of the design and construction concepts as well as the cost of the project.
