The Chamberlain Bridge is a bridge in Bridgetown, the capital and largest city of the nation of Barbados. In 1872, it was a swing bridge across the marine inlet channel of the inner basin of the Careenage (Constitution River) at Carlisle Bay. The outmoded steel structure was dismantled and rebuilt in 2005–2006 as a lifting bridge with the state-of the-art modern technology of an all-composite single-leaf bascule design. This design is a counterweighted bridge span that pivots upward, permitting pleasure craft to pass through an inlet channel. The bridge was built using fibre-reinforced plastic (FRP), which is lighter, long lasting and non-corrosive.
