The Coast Guard has issued a temporary deviation from the regulation governing the operation of the U.S. Highway 90 swing highway bridge across the Chef Menteur Pass, mile 2.8, at Lake Catherine, Orleans Parish, Louisiana. The deviation is necessary to ensure the safety of pedestrians/bikers as they cross the bridge for the Ochsner Ironman 70.3 New Orleans event. This deviation allows the bridge to remain in the closed-to-navigation position continuously during the event.

The bridge owner approved the request for the closure of the U.S. Highway 90 swing bridge crossing the Chef Menteur Pass, mile 2.8, at Lake Catherine, Orleans, Parish, Louisiana. The bridge provides 10 feet vertical clearance in the closed-to-navigation position at mean high water. Currently, according to 33 CFR 117.436, the draw of the U.S. Highway 90 bridge, mile 2.8, shall open on signal; except that, from 5:30 a.m. to 7:30 a.m. Monday through Friday, except Federal holidays, the draw need open only for the passage of vessels. The draw shall open at any time for a vessel in distress. This deviation allows the draw span of the bridge to remain closed to navigation from 7:30 a.m. until 2 p.m. on Sunday, April 21, 2013, while the Ironman contenders travel across the bridge as part of the race course. Navigation on the waterway consists mainly of commercial fishermen and sportsman fishermen. As a result of coordination between the Coast Guard and the waterway users, it has been determined that this closure will not have a significant effect on these vessels. The Coast Guard will inform users through the Local and Broadcast Notice to Mariners of the closure period. There is an alternate route available via The Rigolets Pass to vessel traffic. Vessels that can pass under the bridge in the closed-to-navigation position can do so at any time. The bridge will not be able to open for emergencies.

In accordance with 33 CFR 117.436, 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.
