Coastal Bridge Company, on behalf of the Louisiana Department of Transportation and Development, requested a temporary deviation from the operating schedule on the SR 57 drawbridge across the Dulac Bayou, mile 0.6, at Dulac, Terrebonne Parish, Louisiana.

The bridge has a vertical clearance of 7 feet above mean high water in the closed-to-navigation position and unlimited in the open-to-navigation position. In accordance with 33 CFR 117.5, the draw shall open on signal for the passage of vessels.

This temporary deviation allows the swing bridge to remain closed to navigation for a total of 20 days from 6 a.m. on Monday, March 10, 2014 through 5 p.m. on Saturday, March 29, 2014, except that the bridge will open to pass all waiting vessels at 6 a.m., 12 noon, and 5 p.m. daily. During this time, repairs will be performed to the hydraulic system of the bridge to include removing and replacing the end wedge-drive system hydraulic pressure unit, all end wedge-drive system hydraulic piping, and four end wedge-drive hydraulic cylinders.

During the closure period, the bridge will not be able to open for the passage of vessels except during the scheduled periods of operation. No alternate routes are available during this deviation; however, the bridge owner will attempt to contact all waterway users to keep them abreast of the repair work. Navigation on the waterway consists of small tugs with tows, fishing vessels, and other recreational craft.

In accordance with 33 CFR 117.35, the draw bridge must return to its regular operating schedule immediately at the end of the effective period of this temporary deviation.

This deviation from the operating regulations is authorized under 33 CFR 117.35.
