The bridges consisted of three cast-iron arches, with two stone piers and abutments. The arches were flat segments of circles, the centre one being not less than 240 feet span, rising 24 feet, so that it was 6 feet above high-water at spring tide. The two side arches were of 210 feet span, each rising 18 feet 10 inches. The two piers were 24 feet wide each at the springing, and 30 feet at the base.

The first stone was laid by Admiral Lord Keith early in 1815
