The bridge spans 75ft and each section can be operated independently swinging horizontally.
The bridge opens on the hour and half hour on request on VHF channel 11.
It is manned for two hours either side of high water. While on duty the bridge operatives maintain a listening watch on VHF channels 11 and 16.
The first opening will be as soon as practical two hours before high water. The final opening will be 10 minutes prior to two hours after high water.
Worked example: High Water is 13.18 - the first opening will be 11.30 (allowing time for the operators to stop the traffic and open the bridge). The next openings, if requested will be: 12.00, 12.30, 13.00, 13.30, 14.00, 14.30, and the final opening will be 15.08.
