SUPPLEMENTARY INFORMATION:

The Oregon Department of Transportation has requested that the I-5 Bridges across the Columbia River remain closed to vessel traffic to facilitate heavier than normal roadway traffic volume associated with a fireworks show on July 4, 2016 near the bridges. The I-5 Bridges cross the Columbia River at mile 106.5, and provide three designated navigation channels with vertical clearances ranging from 39 to 72 feet above Columbia River Datum 0.0 while the lift spans are in the closed-to-navigation position. The normal operating schedule for the I-5 Bridges is codified at 33 CFR 117.869. This deviation period is from 9 p.m. to 11:59 p.m. on July 4, 2016. The deviation allows the lift spans of the I-5 Bridges across the Columbia River, mile 106.5, to remain in the closed-to-navigation position, and need not open for maritime traffic during that period. The bridge shall operate in accordance with 33 CFR 117.869 at all other times. Waterway usage on this part of the Columbia River includes vessels ranging from commercial tug and tow vessels to recreational pleasure craft.

Vessels able to pass under the bridges in the closed positions 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 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 drawbridges must return to their 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.
