A 19TH CENTURY bridge spanning a limestone gorge has been restored using 21st Century engineering techniques.

Gunners Pool Bridge was made in Hartlepool in the late 19th Century and is the most impressive of the 16 bridges that cross the Castle Eden Burn at Natural England’s nature reserve on the outskirts of Peterlee, east Durham.

The bridge, designed and commissioned by the Reverend John Burdon, whose family owned Castle Eden Dene, was re-opened yesterday.

The Burdon family owned the dene for 250 years and opened access to the ancient wooded valley by creating footpaths and installing bridges across the gorge.

Gunners Pool Bridge is thought to have been built in June 1877, but has become corroded in recent years.
