Caltrans determined that the original Navy Drive bridge did not meet current safety and design standards. The steel truss only had 14.2 feet of vertical clearance which prevented many trucks from utilizing Navy Drive and was only a two lane bridge without a shoulder. The bridge was a swing type structure allowing for ship traffic. The new bridge will have increased clearance and will be a four lane bridge, it will have a removable center span that will provide an 80\\\' wide and unlimited vertical clearance for ships when removed. The new bridge will improve traffic operations and meet current safety standards.
