The deviation is necessary to complete scheduled repairs necessitated by a bridge allision.

SUPPLEMENTARY INFORMATION:

The BNSF Railway Company has requested a temporary deviation from the operating schedule of the swing span railroad bridge across Bayou Boeuf, mile 10.2, at Amelia, St. Mary Parish, Louisiana. The bridge provides no vertical clearance in the closed-to-navigation position.

In accordance with 33 CFR 117.5, the bridge currently opens on signal for the passage of vessels. This deviation allows the vertical lift span of the bridge to remain in the closed-to-navigation position from 7 a.m. through 11 p.m. on Thursday, December 6, 2012.

The closure is necessary in order to change out a shaft and reducer gear damaged during a bridge allision earlier this year. Notices will be published in the Eighth Coast Guard District Local Notice to Mariners and will be broadcast via the Coast Guard Broadcast Notice to Mariners System.

Navigation at the site of the bridge consists mainly of tows with barges and some recreational pleasure craft. Due to prior experience, as well as coordination with waterway users, it has been determined that this closure will not have a significant effect on these vessels. An alternate route is available by using the GIWW, Morgan City to Port Allen Alternate Route.

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: November 6, 2012.

Bridge Administrator.
