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
8.1 in Bourg, Terrebonne Parish, Louisiana. The vertical clearance of
the bridge in the closed-to-navigation position is 5.17 feet above Mean
High Water Elevation 3.0 feet Mean Sea Level.
In accordance with 33 CFR 117.438(b), the vertical lift span of the
bridge currently opens on signal except that, from 10 p.m. to 6 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 for twelve consecutive days from 6 a.m. Monday, October
25 through 10 p.m. Friday, November 5, 2010.
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. There are no commercial docks or marine type facilities
within one mile of the bridge along Company Canal or Bayou Terrebonne.
The bridge opens for the passage of navigation an average of 53 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. In an
emergency, the bridge can be returned to operation with a 36 hour
notice.
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: July 23, 2010.
David M. Frank,
Bridge Administrator.
