The bridge project, which was awarded to Arborio Corporation for $2.15 million, is slated to be completed July 30, according to the news release.

"During this construction season, the existing bridge will be reconstructed utilizing precast substructure elements founded on piles, with prestressed concrete deck units to form the bridge deck," the release stated.
