SUPPLEMENTARY INFORMATION:

The Port of Corpus Christi Authority has requested a temporary deviation in order to repair the haul rope anchors of the Tule Lake vertical lift span bridge across Corpus Christi—Port Aransas Channel, mile 14.0 at Corpus Christi, Nueces County, Texas. This temporary deviation will allow the bridge to remain in the closed-to-navigation position from 8:30 a.m. to 2:30 p.m. on Tuesday, July 12, on Wednesday, July 13, and on Thursday, July 14, 2005.

The bridge has a vertical clearance of 9.0 feet above mean high water, elevation 1.0 foot Mean Sea Level and 11.0 feet above mean low water, elevation −1.0 foot Mean Sea Level in the closed-to-navigation position. Navigation at the site of the bridge consists mainly of oil tankers and tows with barges. Recreational vessels do not generally transit this segment of the waterway. Due to prior experience, as well as coordination with waterway users, it has been determined that this three-day partial closure will not have a significant effect on these vessels. The bridge normally opens to pass navigation an average of 850 times per month. The bridge opens on signal as required by 33 CFR 117.5. The bridge may not be able to open for emergencies during the closure period. Alternate routes are not available.

In accordance with 33 CFR 117.35(c), this work will be performed with all due speed in order to return the bridge to normal operation as soon as possible. This deviation from the operating regulations is authorized under 33 CFR 117.35.
