SUMMARY: The Coast Guard has issued a temporary deviation from the 
operating schedule that governs the Southern Boulevard (SR 700/80) 
Bridge across the Atlantic Intracoastal Waterway, mile 1024.7, at Palm 
Beach, FL. The deviation is necessary to accommodate the installation 
of a temporary lift bridge. This deviation allows the bridge to remain 
closed to navigation with openings when advanced notice is given during 
the temporary lift bridge installation.

DATES: This deviation is effective without actual notice from April 20, 
2018 through 6 p.m. on April 30, 2018. For the purposes of enforcement,

SUPPLEMENTARY INFORMATION: Johnson Bros. Corporation, on behalf of the 
bridge owner, Florida Department of Transportation, has requested a 
temporary deviation from the current operating regulation that governs 
the Southern Boulevard (SR 700/80) Bridge across the Atlantic 
Intracoastal Waterway, mile 1024.7, at Palm Beach, FL. The deviation is 
necessary to facilitate the installation of a temporary lift bridge 
adjacent to the existing bascule bridge, which will be used during the 
bridge replacement of the Southern Boulevard Bridge. The existing 
bridge is a double-leaf bascule bridge with a vertical clearance of 14 
feet at mean high water in the closed to navigation position. The 
temporary lift bridge will have a vertical clearance of 14 feet in the 
closed position and 65 feet in the lifted position at mean high water.
    The existing bridge operating regulation is set out in 33 CFR 
117.261(w). Under this temporary deviation, the bridge will remain in 
the closed to navigation position from 7 a.m. on April 10, 2018 through 
6 p.m. on April 16, 2018. From 6:01 p.m. on April 16, 2018 through 6 
p.m. on April 30, 2018, both the existing bascule bridge and the 
temporary lift bridge will open with a four (4) hour advanced notice to 
the bridge tender. The vertical clearance will be reduced to 65 feet 
until the completion of the bridge replacement project.
    The Atlantic Intracoastal Waterway is used by a variety of vessels 
including U.S. government vessels, small commercial vessels, 
recreational vessels and tugs and barge traffic. The Coast Guard has 
carefully considered the restrictions with waterway users in publishing 
this temporary deviation.
    For the duration of the temporary lift bridge installation, 7 a.m. 
on April 10, 2018 through 6 p.m. on April 16, 2018, vessels will not be 
allowed to pass through the bridge for safety reasons. From 6:01 p.m. 
on April 16, 2018 through 6 p.m. on April 30, 2018, vessels able to 
pass through the bridge in the closed position may do so at any time. 
The bridge will not be able to open for emergencies and there is no 
immediate alternate route for vessels to pass.
    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 so that vessel operators can arrange their 
transits to minimize any impact caused by the temporary deviation.
    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.

Director, Bridge Branch, Seventh Coast Guard District.
