WELSH WIND UP: Local MPs, motoring organisations and the police have persuaded the Welsh Office to investigate the use of a Second Severn Crossing-style windshield on the Briton Ferry viaduct near Swansea. The action comes after the M4 between junctions 41 and 42 was closed for nearly 19 hours on 4 January this year because of high winds on the viaduct - the second closure of 1998. Last year high winds closed the viaduct five times, once for nearly 16 hours. Consultant Owen Williams, the viaduct's original designer, has been commissioned to carry out a preliminary appraisal of the structure. This will determine whether it can resist the lateral loads caused by such windshielding without expensive strengthening.
