33 CFR Part 117

[Docket No. USCG-2017-0721]

Drawbridge Operation Regulation; Lake Washington Ship Canal, 
Seattle, WA

AGENCY: Coast Guard, DHS.

ACTION: Notice of deviation from drawbridge regulation.

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

SUMMARY: The Coast Guard has issued a temporary deviation from the 
operating schedule that governs the University Bridge across the Lake 
Washington Ship Canal, mile 4.3, at Seattle, WA. The deviation is 
necessary to accommodate drawspan inspections. This deviation allows 
the bridge to operate in single leaf (half span) during inspections.

DATES: This deviation is effective from 9 a.m. on August 9, 2017, to 3 
p.m. on August 10, 2017.

ADDRESSES: The docket for this deviation, USCG-2017-0721 is available

box and click ``SEARCH.'' Click on Open Docket Folder on the line

FOR FURTHER INFORMATION CONTACT: If you have questions on this 
temporary deviation, call or email Mr. Danny McReynolds, Bridge 
Management Specialist, Thirteenth Coast Guard District; telephone 206-
220-7234, email: d13-pf-d13bridges@uscg.mil.

SUPPLEMENTARY INFORMATION: Seattle Department of Transportation, bridge 
owner, requested a temporary deviation from the operating schedule for 
the University Bridge across the Lake Washington Ship Canal, mile 4.3, 
at Seattle, WA, to allow safe inspections of each leaf of the double 
bascule drawspan. The University Bridge provides a vertical clearance 
of 30 feet in the closed-to-navigation position. Vertical clearances 
are referenced to the Mean Water Level of Lake Washington. While the 
bridge operates in single leaf (half span) mode, a horizontal clearance 
of 75 feet is provided. The normal operating schedule for the three 
subject bridge is in 33 CFR 117.1051. During this deviation period, the 
University Bridge is authorized to open half the drawspan to marine 
vessels from 9 a.m. on August 9, 2017, to 3 p.m. on August 9, 2017, and 
from 9 a.m. on August 10, 2017, to 3 p.m. on August 10, 2017.
    Waterway usage on Lake Washington Ship Canal ranges from commercial 
tug and barge to small pleasure craft. Vessels able to pass under the 
bridge in the closed-to-navigation position may do so at anytime. The 
subject bridge will only be able to open the drawspan in single leaf 
for emergencies during this period, and there is no immediate alternate 
route for vessels to pass. The Coast Guard will also inform the users 
of the waterways through our Local and Broadcast Notices to Mariners of 
the change in operating schedule for the bridge so that vessel 
operators can arrange their transits to minimize any impact caused by 
the temporary deviation.
    In accordance with 33 CFR 117.35(e), the drawbridge must return to 
its regular operating schedule immediately at the end of the effective 
period of this temporary deviation. This deviation from the operating 
regulations is authorized under 33 CFR 117.35.

    Dated: July 31, 2017.
Steven Michael Fischer,
Bridge Administrator, Thirteenth Coast Guard District.
