CSX Transportation Inc. requested a temporary deviation for the Louisville and Nashville Railroad Drawbridge, mile 190.4, at Nashville, Tennessee, across the Cumberland River to close the bridge to navigation. The Louisville and Nashville Railroad Drawbridge currently operates in accordance with 33 CFR 117.5, which states the general requirement that drawbridges shall open promptly and fully for the passage of vessels when a request to open is given in accordance with the subpart. In order to meet the bridge owner's request, the deviation period is 8 a.m. to 6 p.m., December 15-18, 2008 for the draw span to remain in the closed-to-navigation position.

There are no alternate routes for vessels transiting this section of the Cumberland River. The bridge has a vertical clearance of 47 feet above normal pool in the closed-to-navigation position. Navigation on the waterway consists primarily of commercial tows, barge fleeter, and recreational watercraft. The majority of vessels can pass under the bridge in the closed position. On average there may be no more than two openings during a week. This temporary deviation has been coordinated with waterway users and no objections were raised.

In accordance with 33 CFR 117.35(e), the drawbridge shall return to its regular operating schedule immediately at the end of the designated time period. This deviation from the operating regulations is authorized under 33 CFR 117.35.
