TRAFFIC is building up along Oxford's ring road near Kennington roundabout.

A contraflow system has been introduced while Oxfordshire County Council turns the junction into a “hamburger” roundabout.

This is currently causing congestion along the A423 back to the Cowley Junction.

Oxford Bus Company has tweeted: "Rush hour traffic is now building up and the Kennington roundabout road works are causing delays. Sorry for any inconvenience."
