Auburn Street Bridge, Mystic Valley Parkway

The Auburn Street Bridge spans the Mystic River. Constructed in 1906, the single-span concrete arch bridge has abutments that act as large-spread footings. Undermining of the abutments and wing walls caused by scour, raised concerns that the bridge would not be able to survive a 500-year flood. As part of an on-call engineering services contract with the Commonwealth of Massachusetts Department of Conservation and Recreation, SGH evaluated potential scour effects and designed countermeasures to protect the bridge foundation during extreme floods.
