# SUPPLEMENTARY INFORMATION:

The Burlington Northern Santa Fe Railway Company has requested a temporary deviation from the operating schedule of the swing span bridge across the Mermentau River at mile 68.0 in Mermentau, Acadia and Jefferson Parishes, Louisiana. The closure is necessary in order to remove and replace the top flanges on four floor beams on the bridge. This maintenance is essential for the continued operation of the bridge.

Presently, the bridge opens on signal for the passage of vessels, as required by 33 CFR 117.5. This deviation will allow the bridge to remain in the closed-to-navigation position from 6:30 a.m. Tuesday, May 18 through 5 p.m. Thursday, May 27, 2010.

                    The vertical clearance of the swing span bridge in the closed-to-navigation position is 10.0 feet above Mean High Water. There are no alternate waterway routes available. Navigation on the waterway consists of tugs with tows, fishing vessels and recreational craft. The bridge opens for the passage of navigation an average of 5 times per month. With sufficient notice, the bridge can be opened for emergencies. Due to prior experience and                           ( print page 25766)                        coordination with waterway users, it has been determined that these closures will not have a significant effect on navigation.                

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: April 26, 2010.

David M. Frank,

Bridge Administrator.
