SUPPLEMENTARY INFORMATION: BNSF has 

requested that the BNSF Swing Bridge 

across the Columbia River 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 the Columbia River will 

be disabled and the bridge will not be 

able to be opened. The BNSF Bridge 

crosses the Columbia River, mile 105.6, 

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 operation the bridge opens on 

signal as required by 33 CFR 117.5. 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 the 

Columbia River, mile 105.6, 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 

swing span will be required to open, if 

needed, for vessels engaged in 

emergency response operations during 

this closure period. The bridge shall 

operate in accordance to 33 CFR 117.5 

at all other times. Waterway usage on 

this stretch of the Columbia River 

includes vessels ranging from 

commercial tug and tow 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 9, 2012.

Drawbridge Operation Regulation; Mile 

359.4, Missouri River, Kansas City, MO 

AGENCY: Coast Guard, DHS.

SUMMARY: The Coast Guard has issued a 

temporary deviation from the operating 

schedule that governs the Harry S. 

Truman Railroad Drawbridge across the 

Missouri River, mile 359.4, at Kansas 

City, Missouri. The deviation is 

necessary to allow the replacement of 

eight wire rope lifting cables that 

operate the lift span. This deviation 

allows the bridge to remain in the 

closed position while the lift cables are 

replaced. 

DATES: This deviation is effective from 

10 p.m. on or about May 15, 2012 

through 10 a.m. on May 18, 2012 and

SUPPLEMENTARY INFORMATION: The 

Canadian Pacific Railway requested a 

temporary deviation for the Harry S. 

Truman Railroad Drawbridge, across the 

Missouri River, mile 359.4, at Kansas 

City, Missouri to remain in the closedto-navigation position for two 60-hour 

individual closures while the eight wire 

rope lifting cables that operate the lift 

span are replaced. The closure period 

will start at 10 p.m. on or about May 15, 

2012 through 10 a.m. on May 18, 2012 

and again from 10 p.m. on or about May 

22, 2012 through 10 a.m. on May 25, 

2012. 

Once the wire rope lifting cables are 

removed, the lift span will not be able 

to open, even for emergencies, until the 

replacement wire rope lifting cables are 

installed. 

The Harry S. Truman Railroad 

Drawbridge currently operates in 

accordance with 33 CFR 117.687, which 

states the draws of the bridges across the 

Missouri River shall open on signal; 

except during the winter season 

between the date of closure and date of 

opening of the commercial navigation 

season as published by the Army Corps 

of Engineers, the draws need not open 

unless at least 24 hours advance notice 

is given. 

There are no alternate routes for 

vessels transiting this section of the 

Missouri River. The Harry S. Truman 

Railroad Drawbridge, in the closed-tonavigation position, provides a vertical 

clearance of 51.3 feet above zero on 

W. B. gage at Kansas City, Missouri. 

Navigation on the waterway consists 

primarily of commercial tows and 

recreational watercraft. This temporary 

deviation has been coordinated with the 

waterway users. 

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 9, 2012.

Bridge Administrator, Western Rivers.
