DEPARTMENT OF HOMELAND SECURITY

Coast Guard

33 CFR Part 117

[Docket No. USCG-2016-0021]


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 Montlake Bridge across the Lake 
Washington Ship Canal, mile 5.2, at Seattle, WA. The deviation is 
necessary to allow the bridge to operate in single leaf mode during day 
light hours, and a full closure (both bascule leafs in the closed-to-
navigation position) during night time hours while work crews replace 
bridge decking. This deviation allows a single leaf opening with a one 
hour advance notice during the day, and remains in the closed-to-
navigation position at night.

DATES: This deviation is effective from 6 a.m. on February 27, 2016 to 
6 p.m. on February 28, 2016.

FOR FURTHER INFORMATION CONTACT: If you have questions on this 
temporary deviation, call or email Mr. Steven Fischer, Bridge 
Administrator, Thirteenth Coast Guard District; telephone 206-220-7282, 
email d13-pf-d13bridges@uscg.mil.

SUPPLEMENTARY INFORMATION: Washington Department of Transportation has 
requested a temporary deviation from the operating schedule for the 
Montlake Bridge across the Lake Washington Ship Canal, at mile 5.2, at 
Seattle, WA. The deviation is necessary to accommodate work crews 
conducting timely bridge deck repairs.
    The Montlake Bridge in the closed position provides 30 feet of 
vertical clearance throughout the navigation channel, and 46 feet of 
vertical clearance throughout the center 60 feet of the bridge; 
vertical clearance references to the Mean Water Level of Lake 
Washington. When half the span is open with a single leaf, 46 feet of 
vertical clearance will be reduced

[[Page 2090]]

throughout the center to 30 feet of the bridge.
    To facilitate this event, the north half of the bridge span, or 
single leaf, will open with at least a one hour advance notice provided 
to the bridge operator from 6 a.m. to 6 p.m. on February 27, 2016. From 
6 p.m. on February 27, 2016 to 5 a.m. on February 28, 2016, the 
Montlake Bridge span will remain in the closed-to-navigation position, 
or full closure. Then, from 5 a.m. to 6 p.m. on February 28, 2016, the 
north half of the bridge span will open with at least a one hour 
advance notice to the bridge operator. The normal operating schedule 
for the Montlake Bridge operates in accordance with 33 CFR 117.1051(e).
    The deviation period is from 6 a.m. on February 27, 2016 to 6 p.m. 
on February 27, 2016 (north single leaf opening if a one hour notice is 
given); from 6 p.m. on February 27, 2016 to 5 a.m. on February 28, 2016 
(remain in the closed-to-navigation position); from 5 a.m. on February 
28, 2016 to 6 p.m. on February 28, 2016 (north single leaf opening if a 
one hour notice is given).
    Waterway usage on the Lake Washington Ship Canal ranges from 
commercial tug and barge to small pleasure craft. Vessels able to pass 
through the bridge in the closed-to-navigation position may do so at 
any time. The bridge will be able to open for emergency vessels in 
route to a call when an hour notice is given to the bridge operator, 
and a single leaf opening will be provided. The Lake Washington Ship 
Canal has 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 vessels 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 designated 
time period. This deviation from the operating regulations is 
authorized under 33 CFR 117.35.

    Dated: January 11, 2016.
Steven M Fischer,
Bridge Administrator, Thirteenth Coast Guard District.
