SUPPLEMENTARY INFORMATION:

The Norfolk Southern Corporation requested a temporary deviation in order to perform maintenance on the Norfolk Southern Railroad vertical lift span bridge across the Black Warrior River, mile 267.8, at Eutaw, Greene County, Alabama. This deviation allows the bridge owner to install drive motors necessary to improve reliability and safe operation of the movable bridge and install new bushings to the primary drive axle. This temporary deviation allows the bridge to remain closed-to-navigation from 8 a.m. until 11 a.m. and from 1 p.m. until 4 p.m. daily, Monday through Thursday, September 19, 2016 Start Printed Page 62368through September 22, 2016 and September 26, 2016 through September 29, 2016. The following week of October 3, 2016 through October 7, 2016 the deviation will allow the bridge to remain closed-to-navigation from 8 p.m. until 4 a.m. daily Monday evening through Friday morning.

The Norfolk Southern Railroad vertical lift span drawbridge currently operates in accordance with 33 CFR 117.5, which states the general requirement that the drawbridge shall open on signal. The bridge has a vertical clearance of 18.3 feet above Bridge Reference Elevation for Navigation Clearance (BRENC), elevation 99.2 feet, in the closed-to-navigation position and 72 feet above BRENC in the open-to-navigation position. Navigation on the waterway consists primarily of tugs with tows and occasional recreational craft. The Coast Guard has coordinated this temporary deviation with the Warrior-Tombigbee Waterway Association (WTWA). The WTWA representative indicated that the vessel operators will be able to schedule transits through the bridge such that operations will not significantly be hindered. Thus, it has been determined that this temporary deviation will not have a significant effect on these vessels.

Vessels able to pass through the bridge in the closed position may do so at anytime and should pass at the slowest safe speed. The bridge will be able to open for emergencies and there are no immediate alternate routes 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.

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.
