Drawbridge Operation Regulations; Duluth Ship Canal (Duluth-
Superior Harbor).

AGENCY: Coast Guard, DHS.

ACTION: Notice of temporary deviation from regulations.

-----------------------------------------------------------------------

SUMMARY: Commander, Ninth Coast Guard District, has issued a temporary 
deviation from the regulation governing the operation of the Duluth 
Ship Canal Aerial Bridge at Mile 0.1 over the Duluth Ship Canal, at 
Duluth, MN, for scheduled maintenance. During this temporary deviation 
the bridge will be secured to masted navigation. Vessels that can pass 
under the bridge without an opening may do so at any time.

DATES: This deviation is effective from 6 a.m. on January 14, 2011 to 
10 a.m. on March 14, 2011.

SUPPLEMENTARY INFORMATION: The City of Duluth, MN, who owns and 
operates this drawbridge, has requested a temporary deviation from the 
current operating regulations set forth in 33 CFR 117.661. The purpose 
of this request is to facilitate structural maintenance of the bridge 
superstructure. The bridge is normally required to open if at least 24 
hours advance notice is provided during the scheduled maintenance 
period. Vessels that can pass under the bridge without an opening may 
do so at any time. The bridge has a horizontal clearance of 300 feet 
and a vertical clearance of 15 feet in the closed position. Mariners 
that require passage between the harbor and Lake Superior with an air 
draft greater than 15 feet may use the Superior Entrance Channel, 
Superior, Wisconsin at any time. Impact to masted navigation is 
mitigated by the close proximity of an alternate route and the reduced 
navigational needs in the harbor during the winter. The most updated 
and detailed marine information for this event, and all bridge 
operations, is found in the Local Notice to Mariners and Broadcast 
Notice to Mariners issued by the Coast Guard. From 6 a.m. on January 
14, 2011 to 10 a.m. on March 14, 2011 the bridge need not open for any 
vessel. 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: September 28, 2010.
Scot M. Striffler,
Bridge Program Manager, Ninth Coast Guard District.
