TRAFFIC delays are mounting this morning due to the closure of Park End Street in Oxford while repair work is carried out on a collapsed sewer.

There are estimates of it taking an extra 15 minutes to travel into the city along Botley Road this morning, and the entire length of Abingdon Road is reported to be slow.

Traffic is also queueing on the A34 both ways at the Botley interchange and at Hinksey Hill.

Traffic is heavy in Beaumont Street, Worcester Street, Botley Road, and all the way back to Eynsham Road in Dean Court.

Oxford Bus Company tweeted: "We are experiencing severe delays on all City services due to roadworks in the city and the A34 being heavily congested Oxford bound."

Stagecoach added: "There are major delays on most routes especially S1 and X30."

Bus passenger Dylan Williams said his half hour journey had taken an hour so far this morning.

Park End Street, at its junction with Hollybush Row, will be closed for the next two weeks while Thames Water repair a partially collapsed sewer. The collapse has been caused by a 'fatberg' a combined mass of fat and other items that have been flushed down the drains and sewers.

Traffic will be diverted along Hythe Bridge Street.

Oxford Bus Company tweeted: “Due to the roadworks in Park End Street, our City services operating in the area are now on diversion.”

Oxfordshire County Council last week warned commuters to expect delays of up to 45 minutes this morning.
