BOSTON BRIDGE UPGRADE

The Summer Street Bridge--built in 1899--is the only known surviving example of an electrically operated, paired leaf, oblique retractile drawbridge. The condition of this 95-year-old Boston landmark was critical: the superstructure was badly corroded from the harsh salt water environment and the substructure was in general disrepair. To preserve this example of 19th century American bridge engineering, officials decided to repair the substructure and replace the superstructure, using key historic bridge components in combination with new structural steel to maintain appearance and historic character. This article highlights the historical significance of the bridge and outlines the proposed rehabilitation.
