The Department of the Navy requested a temporary rule changing the operation of the State Route 23 vertical lift span drawbridge. The change accommodates the additional volume of vehicular traffic that the N'Awlins Air Show generates each year. A large amount of the general public is expected to attend the New Orleans Open House Air Show on each day. The change allows for the expeditious dispersal of the heavy volume of vehicular traffic expected to depart the Naval Air Station, Joint Reserve Base following the event. This event has been held annually on or about the last weekend in October but has not been held since Hurricane Katrina. This year, the event is being held on the weekend of May 1-3, 2009. This temporary deviation will allow the bridge to remain in the closed-to-navigation position from 3:30 p.m. until 6:45 p.m. on Friday, May 1 and Saturday, May 2, 2009 and from 3:30 p.m. until 7:45 p.m. on Sunday, May 3, 2009.

The State Route 23 vertical lift span drawbridge across the Gulf Intracoastal Waterway (Algiers Alternate Route), mile 3.8, at Belle Chasse, Louisiana has a vertical clearance of 40 feet above mean high water in the closed-to-navigation position and 100 feet above mean high water in the open-to-navigation position. Navigation on the waterway consists primarily of tugs with tows, commercial fishing vessels, and occasional recreational craft. Mariners may use the Gulf Intracoastal Waterway (Harvey Canal) to avoid unnecessary delays.

The Coast Guard has coordinated the closure with waterway users, industry, and other Coast Guard units. It has been determined that this closure will not have a significant effect on vessel traffic.

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.
