SUPPLEMENTARY INFORMATION:

The Washington State Department of Transportation has requested that the draw span of the Evergreen Point Floating (SR 520) Bridge remain closed to vessel traffic to accommodate University of Washington commencement ceremony traffic. This deviation allows the bridge to remain in the closed position to allow safe movement of event participants. The Evergreen Point Floating (SR 520) Bridge provides three navigational openings for vessel passage, the movable floating span, subject to this closure, and two fixed navigational openings; one on the east end of the bridge and one on the west end. The fixed navigational opening on the east end of the bridge provides a horizontal clearance of 207 feet and a vertical clearance of 57 feet. The opening on the west end of the bridge provides a horizontal clearance of 206 feet and a vertical clearance of 44 feet. Vessels that are able to safely pass through the fixed navigational openings are allowed to do so during this closure period. Under normal conditions, during this time frame, the bridge operates in accordance with 33 CFR § 117.1049(a) which states the bridge shall open on signal if at least two hours notice is given. This deviation is effective from 9:30 a.m. on June 14, 2014 to 6 p.m. on June 14, 2014. The deviation allows the floating draw span of the SR 520 Lake Washington Bridge to remain in the closed position and need not open for maritime traffic from 9:30 a.m. on June 14, 2014 to 6 p.m. on June 14, 2014. The bridge shall operate in accordance to 33 CFR 117.1049(a) at all other times. Waterway usage on the Lake Washington Ship ranges from commercial tug and barge to small pleasure craft. Vessels able to pass through the bridge in the closed positions may do so at anytime. The bridge will 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 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 effective period of this temporary deviation. This deviation from the operating regulations is authorized under 33 CFR 117.35.

Dated: June 2, 2014.

Bridge Administrator, Thirteenth Coast Guard District.
