SUPPLEMENTARY INFORMATION:

The Washington Department of Transportation, the bridge owner, has requested a temporary deviation from the operating schedule for the Montlake Bridge across Lake Washington Ship Canal, at mile 5.2, at Seattle, WA. The deviation is necessary to accommodate event participates to cross the bridge safely. The Montlake Bridge is a double leaf bascule bridge; and in the closed-to-navigation position provides 30 feet of vertical clearance, and 46 feet of vertical clearance at the center 60 feet of the bridge; vertical clearance references to Mean Water Level of Lake Washington. To facilitate this event, the double bascule span is authorized to remain in the closed-to-navigation position from 10:30 a.m. to 2:30 p.m., and from 4:30 p.m. to 6:30 p.m. on June 9, 2018. The Coast Guard coordinated with the local mariners by requesting any objections via the Local Notice to Mariners.

The normal operating schedule for the Montlake Bridge operates in accordance with 33 CFR 117.1051(e). 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 any time. The bridge will be able to open for emergencies. 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 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.
