SUPPLEMENTARY INFORMATION: Multnomah County (bridge owner) has 
requested a temporary deviation from the operating schedule for the 
Morrison Bridge, mile 12.8, and Hawthorne Bridge, mile 13.1, both 
crossing the Willamette River at Portland, OR. The requested deviation 
is to accommodate the annual Bridge Pedal event. To facilitate this 
event, the draws of theses bridges will be maintained as follows: 
Morrison Bridge provides a vertical clearance of 69 feet in the closed-
to-navigation position; and Hawthorne Bridge provides a vertical 
clearance of 49 feet in the closed-to-navigation position; all 
clearances are referenced to the vertical clearance above Columbia 
River Datum 0.0. The normal operating schedule for these bridges is 33 
CFR 117.897. This deviation allows the Morrison Bridge, and the 
Hawthorne Bridge to remain in the closed-to-navigation position, and 
need not open for maritime traffic from 6 a.m. to 12:15 p.m. on August 
13, 2017. Waterway usage on this part of the Willamette River includes 
vessels ranging from commercial tug and barge to small pleasure craft.
    Vessels able to pass through the bridges in the closed-to-
navigation position may do so at any time. The bridges will be able to 
open for emergencies, and there is no immediate alternate route for 
vessels to pass. The Coast Guard will inform the users of the waterway, 
through our Local and Broadcast Notices to Mariners, of the change in 
operating schedule for the bridges 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 drawbridges must return to 
their regular operating schedules 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: July 6, 2017.
Steven M. Fischer,
Bridge Administrator, Thirteenth Coast Guard District.
