U.S. Coast Guard Bridge Permit

What is the purpose of this permit?
Federal law prohibits the construction of any bridge across navigable waters of the United States unless first authorized by the Coast Guard. The Coast Guard approves the location and clearances of bridges through the issuance of bridge permits or permit amendments, under the authority of the General Bridge Act of 1946, Section 9 of the Rivers and Harbors Act of 1899, and other statutes. This permit is required for new construction, reconstruction or modification of a bridge or causeway over waters of the United States.
Who issues this permit?
United States Coast Guard
What activities require this permit?
Construction or modification of bridges over navigable waters. "Navigable" waters is a legal determination that is not contingent on the waterway actually being navigated. Contact the Coast Guard Bridge Program to determine if a waterway is "navigable" and if the project will require a bridge permit. No other agency has the authority or expertise to make this determination.

Is the decision on my permit dependent on anything besides the information in my application?
Issuance of a permit is dependent on the impacts the proposed project will have on navigation and the environment. The project will need to demonstrate consistency with the Clean Water Act Section 401, Coastal Zone Management Act, Endangered Species Act, National Historic Preservation Act, and a NEPA determination.
How long will it take to review my application?
Permit time frame is generally dictated by the above permit dependencies. There is a mandatory 30-day public comment period. Processing of the permit can take 10 months or longer, depending on complexity, after the Coast Guard receives a complete application package.
