Basis and Purpose

The S41 Swingbridge across Wando River mile 10.0, Cainhoy, Berkeley County, South Carolina has a vertical clearance of 6 feet in the closed position. The operating schedule as published in 33 CFR 117.939 states the draw of the S41 bridge shall open on signal if at least 12 hours notice is given. This regulation has been in effect since 1965.

Local mariners have asked the Coast Guard to evaluate the operating schedule to determine if more frequent openings would improve the accessibility of the waterway to maritime navigation. An estimated 400 recreational boats use the waterway in the local area. However, boaters upriver from the bridge have stated that the bridge's low vertical clearance and requirement for 12-hours notice prevents boaters from accessing waterways, like Charleston harbor and the ocean, on the downriver side of the bridge. The South Carolina Department of Transportation has advised that approximately 1000 to 3000 vehicles per day cross this bridge. The Coast Guard anticipates daily bridge openings during this test a positive impact on navigation with the increased use of the waterway by vessel traffic.

This deviation is effective from 8 p.m. on September 1, 2012 through 5 p.m. on December 31, 2012. The S41 Swingbridge shall open on the hour and the half hour, 24 hours-a-day, seven days-a-week.

Following the test deviation period, the Coast Guard will review the bridge logs from the bridge owner to evaluate the impact of this test on local marine traffic. The Coast Guard will also consider all comments and related materials submitted in response to this test deviation. The Coast Guard will then evaluate whether a permanent change to the operating schedule of the S41 Swingbridge is necessary, and under what conditions the bridge should open.

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.

Dated: August 10, 2012.

Bridge Program Director, Seventh Coast Guard District.
