SUPPLEMENTARY INFORMATION: The Burlington Northern Santa Fe Railroad 
Company requested a temporary deviation from the operating schedule for 
the swing span drawbridge across Des Allemands Bayou, mile 14.0, at Des 
Allemands, St. Charles and Lafourche Parishes, Louisiana. The deviation 
was requested to install two open-deck spans, one on each side of the 
existing swing span, to increase the reliability of bridge opening and 
closing operations.
    The draw currently operates under 33 CFR 117.440(b). The draw of 
the Burlington Northern Santa Fe Railroad Bridge, Mile 14.0, shall open 
on signal Monday through Friday from 7 a.m. to 3 p.m. At all other 
times the draw shall open on signal if at least 4 hours notice is 
given.
    For purposes of this deviation, the bridge will remain closed to 
navigation for two separate dates, 30 hours each, from 6 a.m. April 20, 
2017 through 12 noon, April 21, 2017 and from 6 a.m., April 27, 2017 
through 12 noon, April 28, 2017. During this deviation, vessels will 
not be allowed to pass through the bridge. The bridge has a vertical 
clearance of 3 feet above mean high water in the closed-to-navigation 
position and unlimited in the open-to-navigation position. Navigation 
on the waterway consists of tugs with tows, fishing vessels and 
recreational craft.
    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 bridge. The bridge will not be able to open for 
emergencies and there is no immediate alternate route for vessels to 
pass.
    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: March 17, 2017.
Eric A. Washburn,
Bridge Administrator, Eighth Coast Guard District.
