SUPPLEMENTARY INFORMATION: Multnomah County, Oregon owns the Burnside 
Bridge, crossing the Willamette River, mile 12.4, at Portland, OR, and 
has requested a temporary deviation from the operating schedule. The 
requested deviation is to accommodate bridge repairs and upgrades. To 
facilitate this maintenance, the draw of the subject bridge will be 
authorized to operate in single leaf and open the east leaf of the span 
only. The bridge is also authorized to maintain the west leaf in the 
closed-to-navigation position to marine traffic, and reduce the 
vertical clearance up to ten feet. This deviation period is from 7 a.m. 
on July 1, 2018 to 4 p.m. on October 13, 2018.
    The Burnside Bridge provides a vertical clearance of 41 feet in the 
closed-to-navigation position referenced to Columbia River Datum 0.0, 
and the west leaf will be reduced to 31 feet with scaffolding 
installed. The horizontal clearance for an east leaf opening will be 
100 feet. The normal operating schedule is in 33 CFR 117.897. Waterway 
usage on this part of the Willamette River includes vessels ranging 
from commercial tug and barge to small pleasure craft. The Coast Guard 
contacted all known users of the Willamette River for comment, and we 
received no objections for this deviation.
    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 the 
east side of the span only 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 drawbridge must return to 
its 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: May 23, 2018.
Steven M. Fischer,
Bridge Administrator, Thirteenth Coast Guard District.
