SUPPLEMENTARY INFORMATION: The Louisiana Department of Transportation and Development has requested a temporary deviation from the operating schedule of the swing span bridge across the Mermentau River at mile 7.1 in Grand Chenier, Cameron Parish, Louisiana. The closure is necessary in order to perform physical and mechanical repairs pertaining to the bridge's main span and components. This maintenance is essential for the continued operation of the bridge.

The operating schedule for the bridge is in 33 CFR 117.480 and states the bridge opens on signal; except that, from 6 p.m. to 6 a.m. the draw shall open on signal if at least 4 hours notice is given, for the passage of vessels. This deviation allows the bridge to remain closed to navigation for approximately 5 consecutive days, occurring sometime between April 25, 2011 and May 13, 2011. Exact times and dates for the closures will be published in the Local Notice to Mariners and broadcast via the Coast Guard Broad Notice to Mariners system.

The vertical clearance of the swing span bridge in the closed-to- navigation position is 13.15 feet above Mean High Water, elevation 3.1 feet Mean Sea Level. Vessels are able to transit under the bridge during operations. There is an alternate navigation route via Grand

Lake for vessels unable to pass under the bridge. Navigation on the waterway consists of tugs with tows, fishing vessels and recreational craft. Due to prior experience and coordination with waterway users, it has been determined that the closure will not have a significant effect on navigation.

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: March 15, 2011.

David M. Frank,

Bridge Administrator.
