A bill to amend the act of August 18, 1894, the act of March 3, 1899, the Bridge Act of 1906 and the General Bridge Act of 1946, to provide for civil penalties in certain circumstances.

Establishes a civil remedy (in addition to the criminal sanctions already authorized by law) enabling the Coast Guard to bring actions against operators of drawbridges for improper operation of a drawbridge. Imposes such civil penalties, of up to a $1,000 fine, for: (1) violating any rule or regulation governing drawbridges; and (2) unreasonably delaying the opening of a drawbridge after a reasonable signal has been given.

Provides that it shall not be lawful for any bridge, drawbridge or causeway to obstruct, hazard or endanger the free navigation of any navigable waters of the United States, when such obstruction, harzard or danger results from a failure to keep the bridge, drawbridge or causeway and its accessory works in proper repair.
