ROADWORKS in London Road at the junction of Craven Dene in Newbury are causing traffic chaos for the Monday morning rush hour.
One eastbound lane has been closed and a two-way traffic light system has been installed as Thames Water fixes a leaking water main.
This is causing tailbacks to Thatcham and along the A4 as far as the Waitrose roundabout with the Robin Hood Roundabout at a complete standstill.
The A339 is also blocked as commuters try to turn into Faraday Road.
Journeys are taking more than 30 minutes longer than usual.
