**SUPPLEMENTARY INFORMATION:**
The Delaware Department of Transportation (DELDOT), who owns and operates this bascule type drawbridge, has requested a temporary deviation from the current operating regulations set out in 33 CFR 117.237(c) to facilitate the inspection of the operational equipment within the structure.
The Third Street Bridge, at mile 2.3, across the Christina River in Wilmington, DE has a vertical clearance in the closed position to vessels of 14 feet above mean high water.
Under the regular operating schedule the bridge opens on signal as required by 33 CFR 117.237(c).
Under this temporary deviation, the Third Street Bridge will require two hours advance notice to open, each day from 8 a.m. to 5 p.m., on July 18, 2011 until August 5, 2011. At all other times, the Third Street Bridge will open on signal.
Vessels that can pass under the closed span may do so at all times. There are no alternate routes for vessels transiting this section of the Christina River.
There are three vessels that travel through the bridge several times per week whose vertical clearance surpasses the closed bridge position, requiring an opening of the draw span. DELDOT has coordinated this replacement work with these three waterway users and the Coast Guard will inform the other users of the waterway through our Local and Broadcast Notices to Mariners of the closure periods for the bridge so that vessels can arrange their transits to minimize any impacts caused by the temporary deviation. The bridge may be delayed when opening for an emergency during the proposed equipment inspections.
In accordance with 33 CFR 117.35(e), the drawbridge must return to its regular operating schedule immediately at the end of the designated time period. This deviation from the operating regulations is authorized under 33 CFR 117.35.
Dated: June 23, 2011.
Waverly W. Gregory, Jr.,
Bridge Program Manager. By direction of the Commander, Fifth Coast Guard District.
