SUPPLEMENTARY INFORMATION:

The Seattle Department of Transportation (SDOT) has requested a deviation from the operating schedule of Spokane Street Swing Bridge to install new electrical equipment. SDOT chose this date and time to coordinate a work day during a low tide to minimize any impacts with waterway traffic. The Spokane Street Bridge is located in the Duwamish Waterway, mile 0.3, at Seattle, WA, and provides 55 feet of vertical clearance at center span, and 44 feet of vertical clearance at the east and west sides of the navigation channel while in the closed position. Vessels have unlimited vertical clearance with the swing span in the fully open position. Vertical clearances are referenced to mean high-water elevation.

The deviation period is from 8 a.m. to Noon on June 1, 2015. The deviation allows the Spokane Street Swing Bridge across the Duwamish Waterway, mile 0.3, at Seattle, WA, to remain in the closed-to-navigation position and need not open for maritime traffic from 8 a.m. to Noon on June 1, 2015.

The normal operating schedule for the bridge is in 33 CFR 117.1041, which specifies that the draws of each bridge across the Duwamish Waterway shall open on signal. The deviation period is effective from 8 a.m. to Noon on June 1, 2015, and allows the drawbridge to remain in the closed-to-navigation position. Vessel traffic on the Duwamish waterway consists of vessels ranging from small pleasure craft, sailboats, small tribal fishing boats, and commercial tug and tow, and mega yachts.

Vessels able to pass through the bridge in the closed position may do so at any time, but are requested to transit at a minimum safe speed with no wake for worker safety. 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 effective period of this temporary deviation. This deviation from the operating regulations is authorized under 33 CFR 117.35.
