SUPPLEMENTARY INFORMATION: The Louisiana Department of Transportation 
and Development has requested a temporary deviation from the operating 
schedule of the vertical lift span bridge across Company Canal at mile 
0.4 in Lockport, Lafourche Parish, Louisiana. The vertical clearance of 
the bridge is 5 feet above Mean High Water in the closed-to-navigation 
position and 50 feet above Mean High Water in the open-to-navigation 
position.
    In accordance with 33 CFR 117.438(a), the vertical lift span of the 
bridge currently opens on signal except that, from 6 p.m. to 10 a.m. 
the draw opens on signal if at least 4 hours notice is given. This 
deviation allows the vertical lift span of the bridge to remain closed 
to navigation from 6 a.m. until 6 p.m. Monday through Thursday from 
Monday, June 27, 2011 through Thursday July 14, 2011.
    The closure is necessary in order to replace electrical conductors 
and conduit throughout the bridge structure, including the removal and 
replacement of all navigation lights on the span and fender system. 
This maintenance is essential for the continued operation of the 
bridge. Temporary navigational lighting will be provided during the 
closure and power outage period. Notices will be published in the 
Eighth Coast Guard District Local Notice to Mariners and will be 
broadcast via the Coast Guard Broadcast Notice to Mariners System.
    Navigation on the waterway consists of commercial and recreational 
fishing vessels, small to medium crew boats, and small tugs with and 
without tows. The bridge opens for the passage of navigation an average 
of 16 times per month. There are two alternate waterway routes 
available via the Gulf Intracoastal Waterway east to Bayou Lafourche 
and west to Navigation Canal. Small vessels may pass under the bridge 
while in the closed-to-navigation position provided caution is 
exercised.
    Due to prior experience and coordination with waterway users, it 
has been determined that this closure will not have a significant 
effect on vessels that use the waterway.
    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: April 5, 2011.
David M. Frank,
Bridge Administrator.
