Title 33 › CHAPTER 11 — BRIDGES OVER NAVIGABLE WATERS › SUBCHAPTER I — GENERAL PROVISIONS › § 499
Owners, operators, and tenders of drawbridges over U.S. navigable waters must open the bridge for boats under rules made by the Secretary of the department that runs the Coast Guard. Those rules are legally binding. If a person willfully refuses to open a draw as the rules require, they commit a misdemeanor punishable by a fine between $1,000 and $2,000, by up to one year in jail (for a natural person), or both. The Secretary may also issue and enforce additional drawbridge rules, and those rules should, when practical, include regular scheduled openings to reduce motor vehicle traffic delays. No vessel may signal for a bridge to open for parts that are not needed for navigation or that can be easily lowered, and no one may unreasonably delay opening after a lawful signal; the Secretary will make rules for this. Civil penalties for violating these rules are set by year: up to $5,000 for 2004; $10,000 for 2005; $15,000 for 2006; $20,000 for 2007; and $25,000 for 2008 and later. Penalties require notice and a hearing. The Secretary can assess, collect, or reduce penalties until referral to the Attorney General, and unpaid penalties can be sued in the federal district where the violation happened. Temporary schedule changes of 180 days or less must follow approval, notice, and, if denied, a written explanation within 10 days and a chance to respond. Operators must keep detailed logbooks of each bridge movement, keep them for at least 5 years, and give them to the Secretary on request; these logbook rules are exempt from sections 3501–3521 of title 44.
