The Florida East Coast Railroad Bridge across the St. Johns River, Jacksonville, Florida, is a single leaf bascule bridge with a vertical clearance of 9 feet above mean high water (MHW) measured at the fenders in the closed position and a horizontal clearance of 195 feet.

The current operating regulation in 33 CFR 117.325(c) requires that the bridge be constantly tended and have a mechanical override capability for the automated operation. A radiotelephone must be maintained at the bridge for the safety of navigation. The draw is normally in the fully open position, displaying flashing green lights to indicate that vessels may pass. When a train approaches, large signs on both the upstream and downstream sides of the bridge flash “Bridge Coming Down,” the lights go to flashing red, and siren signals sound. After an eight minute delay, the draw lowers and locks if there are no vessels under the draw. The draw remains down for a period of eight minutes or while the approach track circuit is occupied. After the train has cleared, the draw opens and the lights return to flashing green.

This deviation will facilitate repairs to the upper trunnion of the moveable span. The work will be performed on an around-the-clock basis from 11 p.m. on December 1, 2002, until 5 p.m. on December 12, 2002. During this period of work the span will remain in the closed position.

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.
