Newport is Chaos if there is an accident on the M4 or a concert at the Principality Stadium.

Chepstow Rd becomes chocka block all the way from the Coldra, along the SDR and everything is clogged on the Magor Road that goes past Llanwern and through the roads around the Leeway industrial Estate.

Corporation Road, Caerleon Road and most of the roads on the East Side of Newport come to a complete standstill.

I’ve no idea if the speed limits will hinder things but I can’t see them helping.
