day, and remains in the closed-to-navigation position during evening
hours.
DATES: This deviation is effective from 10 p.m. on August 11, 2017 to 5
a.m. on August 21, 2017.

SUPPLEMENTARY INFORMATION: Washington Department of Transportation
(WSDOT), bridge owner, 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 to conduct timely bridge deck repairs. The
Montlake Bridge in the closed-to-navigation 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 30 feet of the
bridge. To facilitate this construction event, single leaf operation
will provide 75 feet of horizontal clearance.
The normal operating schedule for the Montlake Bridge operates in
accordance with 33 CFR 117.1051(e). The deviation period and span
operation is described in the table below:

----------------------------------------------------------------------------------------------------------------
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
anytime. 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
[[Page 34855]]
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: July 20, 2017.
Steven Michael Fischer,
Bridge Administrator, Thirteenth Coast Guard District.
