33 CFR Part 117

[Docket No. USCG-2018-1054]


Drawbridge Operation Regulation; Duwamish Waterway, 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 Southwest Spokane Street Bridge 
(Spokane Street Bridge), mile 0.3, across the Duwamish Waterway at 
Seattle, WA. The deviation is necessary to accommodate re-routed 
roadway traffic while the Alaskan Way Viaduct is closed. This deviation 
allows the subject bridge to remain in the closed-to-navigation 
position to allow congested roadway traffic to move easier.

DATES: This deviation is effective from 7 a.m. on January 11, 2019, to 
7 p.m. on February 9, 2019.

temporary deviation, call or email Mr. Steven Fischer, Bridge 
Administrator, Thirteenth Coast Guard District; telephone 206-220-7282,

SUPPLEMENTARY INFORMATION: Seattle Department of Transportation (SDOT), 
the owner of the impacted drawbridges, requested a temporary deviation 
from the operating schedule for the Spokane Street Bridge, mile 0.3, 
across the Duwamish Waterway at Seattle, WA, to facilitate morning and 
afternoon re-routed roadway traffic. Washington Department of 
Transportation is closing the Alaskan Way Viaduct forever, and have not 
finished building new ramp approaches to the new SR99 Tunnel into 
Seattle, WA. During the closure of the viaduct, SDOT will be re-routing 
roadway traffic into Seattle across the Duwamish Waterway, and 
requested to not open the subject bridge to marine vessels during 
morning and afternoon hours. The normal operating schedule for the 
Spokane Street Bridge is in 33 CFR 117.5; which is open on signal. The 
Spokane Street Bridge provides a vertical clearance of 55 feet for the 
center 130 feet in the closed-to-navigation position, and 44 feet in 
the closed-to-navigation position on both sides. Vertical clearances 
refer to the Mean High tide level.
    During this deviation period, the Spokane Street Bridge draw need 
not open to vessels from 7 a.m. to 10 a.m., and from 2 p.m. to 5 p.m. 
from January 11, 2019 to February 9, 2019, for vessels less than 5000 
gross tons. If a vessel has in tow a vessel of 5000, or more, gross 
tons, or is a vessel proceeding to pick up a tow vessel of 5000, or 
more, gross tons, the Spokane Street Bridge shall open on signal. Delta 
Marine will be conducting sea trials during this deviation period with 
a 174 foot, 900 ton vessel; SDOT has agreed to open the subject bridge, 
on signal, for the Delta Marine vessel during this deviation period. 
Waterway usage on the Duwamish Waterway range from large mega yachts, 
commercial tug and barge to small pleasure craft. Vessels able to pass 
through the subject bridge in the closed-to-navigation position may do 
so at any time. The Spokane Street Bridge will not be able to open for 
emergencies, 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 bridges 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 Spokane Street Bridge 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: December 3, 2018.
Steven M. Fischer,
Bridge Chief Administrator, Thirteenth Coast Guard District.
