The Cleddau Bridge (Welsh: Pont Cleddau) is a toll bridge on the A477 road that spans the River Cleddau between Neyland and Pembroke Dock, Wales. It was originally called the Milford Haven Bridge. Due to errors in the box girder design it collapsed during construction in 1970 and did not become operational until 1975.Toll booths are located on the Pembroke Dock side of the bridge.
