SUPPLEMENTARY INFORMATION: Washington Department of Transportation has

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, single leaf, 46 feet of 
vertical clearance will be reduced throughout the center to 30 feet of 
the bridge. To facilitate this event, the north half of the bridge span 
will open with at least a one hour advance notice provided to the 
bridge operator from 6 a.m. to 6 p.m. From 6 p.m. to 6 a.m., the 
Montlake Bridge span will remain in the closed-to-navigation position, 
or full closure.
    The deviation period is from 6 a.m. until 6 p.m. on September 24, 
2016 (north single leaf opening if a one hour notice is given); from 6 
p.m. on September 24, 2016 until 6 a.m. on September 25, 2016 (span 
remain in the closed-to-navigation position); from 6 a.m. until 6 p.m. 
on September 25, 2016 (north single leaf opening if a one hour notice 
is given); from 6 p.m. on September 25, 2016 until 6 a.m. on September 
26, 2016 (span remain in the closed-to-navigation position). The normal 
operating schedule for the Montlake Bridge operates in accordance with 
33 CFR 117.1051(e).
    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: August 25, 2016.

Bridge Administrator, Thirteenth Coast Guard District.
