Per this Chattanooga Times Free Press article, the U.S. House approved a bill that would raise a barge fuel tax to fund various inland waterway projects including the Chickamauga Lock.

(According to the article, Rep. Chuck Fleischmann attached the proposed fuel tax increase to a bill allowing people with disabilities to create special accounts for tax-free savings. Whatever.)

Anyway, the bill would provide $40 million per year in additional funding for inland waterway projects. According to the article, the cost of the new Chickamauga lock is $860 million and $180 million has already been spent, leaving $680 million needed.

So if all of the new $40 million in funding went just for the Chickamauga project, it would take 17 years to complete? Or am I missing something?
