Louisiana Department of Transportation and Development (LDOTD) has requested a temporary deviation from the operating schedule of the State Route 661 Swing Bridge across the Houma Navigation Canal, mile 36.0, in Houma, Terrebonne Parish, Louisiana. The closure is necessary to allow for repairs to the bridge.

Presently, the bridge operates in accordance with 33 CFR 117.455 which requires the draw of the bridge across the Houma Navigation Canal at S661, mile 36.0 at Houma, to open on signal, except that the draw need not be opened for the passage of vessels Monday through Friday except holidays from 7 a.m. to 8:30 a.m., from 11:45 a.m. to 12:15 p.m., from 12:45 p.m. to 1:15 p.m., and 4:30 p.m. to 6 p.m. This deviation will allow the bridge to remain in the closed-to-navigation position from 6 a.m. on Wednesday, July 22, 2009 until 6 a.m. on Thursday, July 23, 2009. Navigation on the waterway consists of tugs with tows, fishing vessels and recreational craft. Due to prior experience and coordination with waterway users it has been determined that this closure will not have a significant effect on these vessels.

The vertical clearance of the swing bridge in the closed-to-navigation position is 1.0 feet and unlimited in the open-to-navigation position. An alternate route is available through La Carpe Bayou. During the deviation period, LDOTD will provide drawtenders for the State Route 661 bridge across La Carpe Bayou, mile 7.5 to open the bridge on signal; except that, the draw need not be opened for the passage of vessels from 7 a.m. until 8:30 a.m. and from 4:30 p.m. until 6 p.m. At the end of the deviation period the La Carpe Bayou bridge will return to its operating schedule in accordance with 33 CFR 117.461. As this work is proposed during hurricane season, if any storms are in the Gulf of Mexico, the work may be postponed and rescheduled.

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.
