St. Catherine's Bridge

Richard - at last, 9 years working for the National Rivers Authority & Environment Agency comes in hand - St. Catherine's Bridge is between Camrose and Withybush Airfield. Easiest way to describe it is turn left towards Camrose off the A40 (as you head towards Fishguard) at the N end of Withybush Airfield, and it's at the bottom of the hill, just beyond West Wales Activity Toys:

I also have an unrivalled knowledge of Pembrokeshire sewage works - sometimes handy, often not.
