SUPPLEMENTARY INFORMATION: Oregon Department of Transportation (bridge 
owner) requested a temporary deviation from the operating schedule for 
the I-5 Bridge, north bound, mile 106.5, across the Columbia River 
between Vancouver, WA, and Portland, OR, to align lift span operating 
rope drive gear and sheave bearing clearances. The I-5 Bridge provides 
three designated navigation channels with vertical clearances ranging 
from 39 to 72 feet above Columbia River Datum 0.0 while the lift span 
is in the closed-to-navigation position. The normal operating schedule 
for the I-5 Bridge is 33 CFR 117.869. The deviation is effective from 
12:01 a.m. on September 10, 2018 until 11:59 p.m. on September 19, 
2018. The I-5 Bridges (north bound) are to remain in the closed to 
navigation position for the duration of the deviation, and need not be 
raised upon signal. Waterway usage on this part of the Columbia River 
includes vessels ranging from large commercial ships and tug and tow 
vessels to recreational pleasure craft.
    Vessels able to pass under the bridge in the closed-to-navigation 
positions may do so at any time. The bridge will not be able to open 
for emergencies, and there is no immediate alternate route for vessels 
to pass except for the fixed height spans. 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.

    Dated: August 22, 2018.
Steven M. Fischer,
Bridge Administrator, Thirteenth Coast Guard District.
