# 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.
