Electronic information boards - similar to those seen on motorways - will be installed on A roads leading in to Oxford, it was confirmed today.

Six signs were today given the go ahead by Oxfordshire County Council, which said they provide information on accidents, roadworks and car parking.

The council said the boards, which will be switched on in spring 2009, would eventually be used to display journey times to the city centre by bus, journey time to the next car park and routes with abnormally high congestion.

The A40 will receive three of the signs positioned near the Thornhill Park-and-Ride, near the Eynsham roundabout and before the Wolvercote roundabout.

Other boards will be placed on the A420 at the Cumnor slip road, the A4074 near the Sandford-on-Thames turn and the A44 south of Yarnton.

£350,000 of the £480,000 project will be come from developer contributions as part of the deal to expand the Westgate Centre.
