SUPPLEMENTARY INFORMATION:

SDOT, the bridge owner, has requested a temporary deviation from the operating schedule for the Fremont Bridge, mile 2.6, crossing the Lake Washington Ship Canal at Seattle, WA. The deviation is necessary to accommodate heavy pedestrian traffic crossing the bridge during the Lake Union 10K Run event. To facilitate this event, the double bascule draw of the bridge will not open for vessel traffic during the stated date and times. The Fremont Bridge provides a vertical clearance of 14 feet (31 feet of vertical clearance for the center 36 horizontal feet) in the close-to-navigation position. The clearance is referenced to the mean water elevation of Lake Washington. The normal operating schedule for the Fremont Bridge is found in 33 CFR 117.1051. Waterway usage on the Lake Washington Ship Canal ranges from commercial tug and barge to small pleasure craft. No early Sunday morning bridge opening requests have been received during August for the Fremont Bridge in the last five years.

Vessels able to pass through the bridge in the closed-to-navigation position 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 waterway 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: July 6, 2017.

Steven M. Fischer,

Bridge Administrator, Thirteenth Coast Guard District.
