SUPPLEMENTARY INFORMATION:

The Seattle Department of Transportation has requested a temporary deviation from the operating schedule for the University Bridge, mile 4.3, across the Lake Washington Ship Canal at Seattle, WA. The requested deviation is to allow King County Metro Transit to perform essential maintenance on the University Bridge. The plan is to re-cable all the metro trolley lines on the bridge. To facilitate this maintenance period, the draws of the bridge will be maintained in the closed-to-navigation position on July 11th, 12th, and 13th, 2014 from 10 p.m. to 8 a.m. the following morning, then again on the 18th, 19th, and 20th, 2014 from 10 p.m. to 8 a.m. the following morning. Vessels which do not require bridge openings may continue to transit beneath the bridge during the closure periods. The University Bridge, mile 4.3, provides a vertical clearance of 30 feet in the closed position; clearances are referenced to the mean water elevation of Lake Washington. The current operating schedule for the bridge is set out in 33 CFR 117.1051. The normal operating schedule for the University Bridge states that the bridge need not open from 7 a.m. to 9 a.m. and from 4 p.m. to 6 p.m. Monday through Friday for vessels less than 1000 tons. The normal operating schedule for the bridge also requires one hour advance notification for bridge openings between 11 p.m. and 7 a.m. daily. 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 positions may do so at anytime. The 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 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: June 25, 2014.

Steven M. Fischer,

Bridge Administrator, Thirteenth Coast Guard District.
