Tampa Bypass Canal The Tampa Bypass Canal and Palm River are a 14 mi flood bypass operated by the Southwest Florida Water Management District. The canal includes several concrete flood control structures and was constructed during the 1960s and 1970s. Its purpose is to redirect flood waters from large amounts of rainfall from the Hillsborough River to Tampa Bay to prevent floodwaters reaching homes and businesses. Despite its original purpose it is now used as a drinking water source for the City of Tampa. During construction of the canal the Floridan aquifer was accidentally breached.
St. Georges Bridge (Delaware) The St. Georges Bridge is a steel truss bridge with a tied arch span that carries U.S. Route 13 (US 13) across the Chesapeake & Delaware Canal in St. Georges, Delaware. Built by the U.S. Army Corps of Engineers and opened in 1942 as a high-level crossing, the bridge was the first four-lane, high-level crossing to span the canal. It replaced a previous vertical lift bridge which was damaged when a German merchant ship collided with it.
