In order to perform necessary maintenance, the Louisiana Department of Transportation and Development has requested a temporary deviation from the published regulation for the SR 39 (Judge Seeber/Claiborne Avenue) vertical lift bridge across the Inner Harbor Navigational Canal, mile 0.9, (GIWW mile 6.7 EHL). The bridge provides 40 feet of vertical clearance when closed above mean high water, and 156 feet above MHW in the open-to-navigation position. Currently, under 33 CFR 117.458(a), the draw of the bridge shall open on signal; except that, from 6:30 a.m. to 8:30 a.m. and 3:30 p.m. to 5:45 p.m. Monday through Friday, the draw need not be open for the passage of vessels. The draw shall open at any time for a vessel in distress.

This deviation allows the bridge to remain closed to navigation from 6:30 a.m. until 5:45 p.m. from April 2, 2011 through May 21, 2011. However, during these times, the bridge will open for the passage of vessels at 10 a.m. and 2 p.m. daily. From 5:45 p.m. until 6:30 a.m., the bridge will remain in the open-to-navigation position or will open on signal. Exact times and dates for the closures will be published in the Local Notice to Mariners and broadcast via the Coast Guard Broadcast Notice to Mariners system.

Navigation on the waterway consists mainly of tugs with tows and ships. The Coast Guard has coordinated the closure with waterway users, industry, and other Coast Guard units. These dates and this schedule were chosen to minimize the significant effects on vessel traffic; however, vessels that can pass under the bridge in the closed-to-navigation position can do so any anytime. The bridge will not be able to open for emergencies.Start Printed Page 8654

The bridge 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.
