Coast Guard

33 CFR Part 117

[Docket No. USCG-2016-0978]


Drawbridge Operation Regulation; Pass Manchac, Manchac, LA

AGENCY: Coast Guard, DHS.

ACTION: Notice of deviation from drawbridge regulations.

-----------------------------------------------------------------------

SUMMARY: The Coast Guard has issued a temporary deviation from the 
operating schedule that governs the Canadian National (CN) Railroad 
automated bascule span drawbridge across Pass Manchac, mile 6.7 at 
Manchac, between St. John and Tangipahoa Parishes, Louisiana. The 
deviation is necessary to accommodate bridge repair work essential for 
the continued operation of the bridge. This deviation allows the bridge 
to remain closed-to-navigation for eight hours on three consecutive 
days, allowing vessels to pass with a one-hour advance notice.

DATES: This deviation is effective from November 15, 2016 through 
November 17, 2016 from 5 a.m. through 2 p.m.

ADDRESSES: The docket for this deviation, [USCG-2016-0978] is available 
at http://www.regulations.gov.

FOR FURTHER INFORMATION CONTACT: If you have questions on this 
temporary deviation, call or email Donna Gagliano, Bridge 
Administration Branch, Coast Guard, telephone (504) 671-2128, email 
[email protected].

SUPPLEMENTARY INFORMATION: CN Railroad, requested that a one-hour 
advance notice be given for the passage of vessels on the automated 
bascule span drawbridge across Pass Manchac, mile 6.7 at Manchac, 
between St. John and Tangipahoa Parishes, Louisiana. The deviation is 
necessary to replace the rail, fasteners, and lift joints on the 
bridge. This work is essential for the continued operation of the 
bridge.
    In accordance with 33 CFR 117.484, the bridge is not tended and is 
therefore automated. These operations are described in 33 CFR 117.484. 
Currently, the bridge remains open until the passage of a train at 
which time it closes to allow the train to pass. This deviation will 
allow the bridge to remain closed to all marine traffic from 5 a.m. 
through 2 p.m. on Tuesday, November 15, 2016 through Thursday, November 
17, 2016, without a one-hour advance notice.
    The bridge will remain operational to vessels with a one-hour 
advanced notice. A tender will be on site to operate the bridge during 
the set work schedule and will be monitoring channel 16.
    Navigation on the waterway consists of small tugs with and without 
tows, commercial vessels, and recreational craft, including sailboats. 
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 to minimize any impact caused by the temporary 
deviation. The bridge will be unable to open during these repairs and 
no alternate route is available.
    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: October 31, 2016.
David M. Frank,
Bridge Administrator, Eighth Coast Guard District.
