Mississippi Department of Transportation (MDOT), the bridge owner, requested a 24 hour notice be given to open the I-110 Bridge over the Back Bay of Biloxi, Mile 3.0, between Biloxi and D'Iberville, Harrison County, MS. The bridge has a horizontal clearance of 132 feet and a vertical clearance of 60 feet, above Mean Sea Level, in the closed-to-navigation position and an unlimited vertical clearance in the open-to-navigation position.

The bridge opens per 33 CFR 117.675(a). This regulation states that the I-110 Bridge opens on signal if at least 6-hours notice is given. The deviation will require a 24 hour notice to operate the bridge from November 1, 2013 through April 29, 2014. This schedule will allow the safe and continued rehabilitation and maintenance of the bridge.

This waterway is used by both commercial and recreational vessel traffic. No previous coordination was made with the waterway users though the closure dates were chosen to minimize the impact to these users.

Vessels able to pass through the bridge in the closed positions may do so at anytime. 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 vessels 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.
