I’d like to say thanks for all your help in competing the remedial works to Crickhowell and Llangynidr bridges ready for another winter. Dean and his team worked well, were professional at all times and really easy to work with. CADW are happy with the repairs and we have even had a few locals stop and say how great the repairs look.
