It shall be the duty of all persons owning, operating, and tending the drawbridges built prior to August 18, 1894, or which may thereafter be built across the navigable rivers and other waters of the United States, to open, or cause to be opened, the draws of such bridges under such rules and regulations as in the opinion of the Secretary of Transportation the public interests require to govern the opening of drawbridges for the passage of vessels and other water crafts, and such rules and regulations, when so made and published, shall have the force of law. Every such person who shall willfully fail or refuse to open, or cause to be opened, the draw of any such bridge for the passage of a boat or boats, as provided in such regulations, shall be deemed guilty of a misdemeanor, and on conviction thereof shall be punished by a fine of not more than $2,000 nor less than $1,000, or by imprisonment (in the case of a natural person) for not exceeding one year, or by both such fine and imprisonment, in the discretion of the court: Provided, That the proper action to enforce the provisions of this subsection may be commenced before any magistrate judge, judge, or court of the United States, and such magistrate judge, judge, or court shall proceed in respect thereto as authorized by law in case of crimes against the United States: Provided further, That whenever, in the opinion of the Secretary of Transportation, the public interests require it, he may make rules and regulations to govern the opening of drawbridges for the passage of vessels and other water crafts, and such rules and regulations, when so made and published, shall have the force of law, and any willful violation thereof shall be punished as hereinbefore provided: Provided further, That any regulations made in pursuance of this section may be enforced as provided in section
413 of this title, the provisions whereof are made applicable to the said regulations. Any rules and regulations made in pursuance of this section shall, to the extent practical and feasible, provide for regularly scheduled openings of drawbridges during seasons of the year, and during times of the day, when scheduled openings would help reduce motor vehicle traffic delays and congestion on roads and highways linked by drawbridges.
