SUPPLEMENTARY INFORMATION: Amtrak, the owner of the bridge, requested a 
temporary deviation in order to facilitate installation of a lift span 
emergency generator. The Amtrak Bridge across the Thames River, mile 
3.0 at New London, Connecticut has a horizontal clearance of 150 feet 
and a vertical clearance of 29 feet at mean high water and 31 feet at 
mean low water in the closed position. The bridge has a vertical 
clearance of 75 feet in the intermediate raised position and 135 feet 
in the fully open position at mean high water. The existing drawbridge 
operating regulations are listed at 33 CFR 117.224.
    This temporary deviation will allow the Amtrak Bridge to require a 
2 hour advance notice between 9 p.m. and 7 a.m. from July 31, 2017 to 
September 12, 2017, while a crane barge is present next to the lift 
span. The presence of the crane barge reduces the horizontal clearance 
to 70 feet. Additionally, between July 31, 2017 and September 10, 2017 
the lift span will be in the down position during daytime hours but 
will be able to open when requested.
    The waterway is transited by recreational traffic, commercial 
vessels, ferries, and military vessels. Vessels that can pass under the 
bridge without an opening may do so at all times. When the barge is 
located next to the lift span, the bridge will not be able to open 
immediately for emergencies. There is no alternate route for vessels 
unable to pass through the bridge when in the closed position.
    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 this 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.
