SUPPLEMENTARY INFORMATION: The CSX Transportation has requested a 
temporary deviation from the operating schedule for the Swing Span 
Bridge across Chickasaw Creek, mile 0.0, in Mobile, Alabama. The bridge 
has a vertical clearance of 6 feet above mean high water in the closed-
to-navigation position and unlimited in the open-to-navigation 
position.
    In accordance with 33 CFR 117.5, the bridge currently opens on 
signal for the passage of vessels. This deviation allows the bridge to 
remain closed to navigation for two (2) four-hour periods on two 
consecutive days with a one-hour opening in the middle of the closures. 
The bridge will remain closed to navigation from 7 a.m. until 11 a.m. 
and from noon until 4 p.m. on Tuesday, February 8, 2011 and Wednesday, 
February 9, 2011. At all other times, the bridge will open on signal 
for the passage of vessels.
    The closure is necessary in order to change out railroad ties on 
the bridge. This maintenance is essential for the continued operation 
of the bridge. 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 mainly of tugs with tows and 
ships. As a result of coordination between the Coast Guard and the 
waterway users, this closure has been scheduled to minimize the 
possibility of any significant effects on these vessels. There are no 
alternate routes available to vessel traffic. The bridge will not be 
able to open for emergencies.
    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: January 3, 2011.
David M. Frank,
Bridge Administrator.
