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 electrical and mechanical repairs 
pertaining to the bridge's main span drive assembly and system 
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 will allow the bridge to remain 
in the closed-to-navigation position from 7 a.m. Wednesday, April 21, 
2010, through 7 a.m. Thursday, July 1, 2010.
    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 30, 2010.

Bridge Administrator.
