Price tag on Freeport bridge replacement looks more palatable after DOT revises estimate The I-295 Exit 20/Desert Road interchange overpass and the Exit 22/Mallet Dive interchange overpass, built in 1957, have been deemed structurally deficient and are slated to be replaced. Town officials hope to add two multi-use paths to increase the Freeport's connectivity. Shawn Patrick Ouellette / The Portland Press Herald FREEPORT — Freeport town officials are breathing a sigh of relief after receiving word that the price tag on $1.2 million bridge replacement and sidewalk installation project could be cut nearly in half, though numbers are still being crunched. The I-295 Exit 20/Desert Road interchange overpass and the Exit 22/Mallet Dive interchange overpass, built in 1957, have been deemed structurally deficient and are slated to be replaced through a $19 million Competitive Highway Bridge Program Grant awarded last year.
