Tidal flood defences designed to protect more than 200 homes in Truro were unveiled yesterday.
The £3 million scheme by the Environment Agency and Cornwall Council includes a new wall at Lighterage Quay and raised flood banks in Boscawen Park across the river.
The flood alleviation project was opened by Truro and Falmouth MP Sarah Newton, Lord Chris Smith, chairman of the Environment Agency, and council leader Alec Robertson.
Mrs Newton said the new defences had “transformed” the quay, and would be a real asset for the city.
“The flooding back in 1988 was very bad and had a terrible effect on the businesses and homes in this area,” she added.
“It was essential this important work was carried out so we can try to avoid the worst effects of extreme high tides in the future.”
