Hawarden Bridge (/ˈhɑːrdən/; Welsh: Pont Penarlâg) is a railway bridge over the River Dee, near Shotton, Flintshire, Wales. It was built by the Manchester, Sheffield and Lincolnshire Railway (which later became the Great Central Railway), as part of the Chester & Connah's Quay Railway. It opened on 3 August 1889. The central section, which was designed as a swing bridge to allow shipping to pass, no longer opens and is welded shut, although the rotating mechanism - hydraulic cylinders attached to a drive chain and sprocket - is still visible beneath the bridge.
