SUPPLEMENTARY INFORMATION:

The Port of Corpus Christi Authority has requested a temporary deviation in order to remove and replace the main drive bearings of the Tule Lake vertical lift span bridge across Corpus Christi—Port Aransas Channel, mile 14.0 at Corpus Christi, Nueces County, Texas. This maintenance is essential for the continued safe operation of the bridge. This temporary deviation will allow the bridge to remain in the closed-to-navigation position from 7 a.m. through 7 p.m. on Thursday, May 22, 2003.

The vertical lift span bridge has a vertical clearance of 9.0 feet above mean high water, elevation 1.0 feet Mean Sea Level and 11.0 feet above mean low water, elevation −1.0 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. There is no recreational pleasure craft usage at the bridge site. Due to prior experience, as well as coordination with water way users, it has been determined that this one day 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 will 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.

Dated: May 7, 2003.

Bridge Administrator.
