SUPPLEMENTARY INFORMATION: The Louisiana Department of Transportation 
and Development (LADOTD) requested a temporary deviation from the 
operating schedule of the State Route 433 Bridge across Bonfouca Bayou, 
mile 7.0, at Slidell, St. Tammany Parish, Louisiana. This deviation is 
necessary to accommodate the removal and replacement of the open grid 
steel deck on the movable section of the swing bridge, which will take 
place seven days a week during nighttime hours. The vertical clearance 
of the bridge is 8 feet above mean high water (MHW) in the closed-to-
navigation position and unlimited in the open-to-navigation position. 
There is 125 feet of fender to fender horizontal clearance. The bridge 
currently operates under 33 CFR 117.433.
    This deviation is effective from 6 p.m. on Saturday, October 27, 
2018, through 6 a.m. on Friday, December 7, 2018. During the deviation 
period, the bridge will be closed-to-navigation from 6 p.m. to 6 a.m., 
Monday through Friday, and from 6 p.m. to 9 a.m. on Saturday and 
Sunday, including holidays. At all other times, the bridge will operate 
in accordance with 33 CFR 117.433.
    During the nighttime repair periods when the bridge is in the 
closed-to-navigation position, vessels will not be allowed to pass 
through the bridge and the bridge will not be able to open for 
emergencies. Navigation on the waterway consists mainly of recreational 
craft, with some tugs with tows. There is no alternative route. The 
Coast Guard will 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 vessel operators can arrange their transits to 
minimize any impact caused by the temporary deviation.
    In accordance with 33 CFR 117.35, 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 16, 2018.

Bridge Administrator, U.S. Coast Guard Eighth District.
