The Norfolk Southern Railroad requested a temporary deviation for the Southern Railroad Drawbridge, across the Tennessee River, mile 304.4, at Decatur, AL.

The vertical clearance of the bridge in the closed position is 10.5 feet. The bridge opens on request or by signal as required by 33 CFR 117.5. The deviation period is from 8:00 a.m. to noon and from 12:30 p.m. to 4:30 p.m. July 16 through July 19, 2012. The Coast Guard will inform the public through broadcast notices to mariners of any changes in the schedule for this deviation. During the deviation period new rail joints will be installed which require steel cutting and welding activity on the bridge.

Vessel traffic consists of commercial tows ranging from a single barge to 15-barges and approximately six openings during the deviation period could normally occur. This deviation was coordinated with the commercial waterway users and no objections were expressed. The bridge, in the closed position, does not provide ample clearance for vessels to pass beneath and there are no alternate routes for vessels transiting this section of the Tennessee River.

In accordance with 33 CFR 117.35(e), the drawbridge must 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.

Dated: June 18, 2012.

Eric A. Washburn,

Bridge Administrator, Western Rivers.
