DID YOU KNOW? 🌊 If you regularly travel between Benfleet and Canvey, you’ve probably passed the Benfleet Flood Barrier hundreds, maybe thousands, of times. But have you ever wondered what it actually does?
Officially opened in 1983, this impressive bit of local engineering is around 90 metres wide and has three huge steel gates, each weighing roughly 30 tonnes!
Most of the time the gates are raised out of the way, allowing boats and the tide to pass underneath. But when a dangerously high tide is predicted, they can be lowered into position, effectively closing off the creek and helping protect low-lying parts of Benfleet and Canvey from tidal flooding.
So what happens to all that water when the gates are closed? 🌊 It doesn’t disappear! The barrier stops the exceptionally high tidal water pushing further into Benfleet Creek, so the surge is effectively held back on the seaward side until the tide begins to fall. Once conditions are safe again, the gates can be raised and the creek returns to normal.
And here’s a fact you definitely can’t see from the road, the foundations required piles driven more than 100 feet down through Benfleet clay to reach solid ground!
Quite an impressive bit of engineering quietly doing its job beside one of the busiest roads in the area. Interesting, eh! 🌊
