Railway Bridge across Oregon Slough, mile 3.2, at Hayden Island, OR. 
This deviation is necessary to accommodate maintenance of the train 
signaling system scheduled for April 30, 2012. This deviation allows 
the bridge to remain in the closed position for the duration of the 
maintenance activity.

DATES: This deviation is effective from 8 a.m. to 8 p.m. on April 30, 
2012.

SUPPLEMENTARY INFORMATION: BNSF has requested that the BNSF Swing 
Bridge across Oregon Slough remain closed to vessel traffic to 
facilitate maintenance of the train signaling system. BNSF will be 
``cutting over'' the train signaling system to a new system on April 
30, 2012. During this cut-over the swing span of the BNSF Railway 
Bridge across Oregon Slough will be disabled and the bridge will not be 
able to be opened. The BNSF Bridge crosses Oregon Slough at mile 3.2 
and in accordance to NOAA Chart 18526 provides 39 feet of vertical 
clearance above Columbia River Datum 0.0 while in the closed position. 
Vessels which do not require a bridge opening may continue to transit 
beneath the bridge during this closure period. Under normal conditions 
this bridge operates in accordance with 33 CFR 117.887 which requires a 
half-hour advance notification when a bridge opening is needed. This 
deviation period is from 8 a.m. on April 30, 2012 through 8 p.m. April 
30, 2012. The deviation allows the swing span of the BNSF Railway 
Bridge across Oregon Slough, mile 3.2, to remain in the closed position 
and need not open for maritime traffic from 8 a.m. through 8 p.m. on 
April 30, 2012. The bridge shall operate in accordance to 33 CFR Sec.  
117.887 at all other times. Waterway usage on this stretch of Oregon 
Slough includes vessels ranging from commercial sightseeing vessels to 
recreational pleasure craft including cabin cruisers and sailing 
vessels. Mariners will be notified and kept informed of the bridge's 
operational status via the Coast Guard Notice to Mariners publication 
and Broadcast Notice to Mariners as appropriate.
    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: April 3, 2012
Randall D. Overton,
Bridge Administrator.
