SUPPLEMENTARY INFORMATION: The Louisiana Department of Transportation 
and Development has requested a temporary deviation from the operating 
schedule of the swing span bridge across Teche Bayou at mile 56.7 in 
Morbihan, Iberia Parish, Louisiana. The closure is necessary in order 
to rehabilitate machinery parts on the bridge. The work will require 
the bridge to be jacked up and taken out of service. This maintenance 
is essential for the continued operation of the bridge.
    In accordance with 33 CFR 117.501(a)(18), the swing span of the 
bridge shall open on signal if at least 4 hours notice is given. This 
deviation allows the swing span of the bridge to remain closed to 
navigation for three consecutive weeks between 6:30 a.m. Monday, June 
21 and 6:30 a.m. Tuesday, August 3, 2010. Uncontrollable variables such 
as material supply delays and inclement weather make it difficult to 
predict the exact dates that work can be conducted. Thus, the exact 
dates for the closure cannot be firmly scheduled. 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 as soon as information pertaining to the exact closure dates 
becomes available. The Coast Guard will coordinate the closure with the 
commercial users of the waterway as exact closure dates are known.
    The vertical clearance of the swing span bridge in the closed-to-
navigation position is 6.12 feet above Mean high Water Elevation 5.7 
feet Mean Sea Level. Navigation on the waterway consists of tugs with 
tows, ship fabricator's commissioned vessels, crew boats and oil field 
support/service vessels. The bridge opens for the passage of navigation 
an average of 26 times per month. There are no alternate waterway 
routes available. Due to prior experience and coordination with 
waterway users, it has been determined that this closure will not have 
a significant effect on these vessels.
    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.
