With all this bad weather it’s worth highlighting a post I did earlier this year on travel information if you’re travelling by road to, or through, South Wales – http://www.south-wales.org/2009/m4-motorway-traffic-cams/
My Useful South Wales links page also has other travel resources that you may find useful – http://www.south-wales.org/useful-south-wales-links/ especially if you’re travelling by train, coach or plane.
