A Westminster inquiry into the future of the Severn Bridges opened today with evidence from business leaders and hauliers' representatives.

The Welsh Affairs Select Committee will hear from witnesses at its House of Commons hearing today about the impact Severn Bridge tolls have on the Welsh economy, and how much is being spent maintaining them.

Committee members will be looking at the level of tolls and methods of payment, the impact on tourism, the condition of the bridges and the future of the bridges when they return to public ownership.

Monmouth MP David Davies, who chairs the committee, has said he expects the bridges to be handed back to the government around 2016. They are currently operated by Severn Crossings plc.

Those giving evidence in the inquiry include representatives of the Federation of Small Businesses, the Chartered Institute of Logistics, the Freight Transport Association, alongside academics from Aberystwyth University.

Mr Davies has already stated how the committee has "huge concerns" regarding the cost of the bridge to both individuals and businesses and Jessica Morden, MP for Newport East and a member of the committee, has also campaigned for a freeze on the tolls in the past.

In July the Department of Transport also revealed how almost £18 million of taxpayers' money was given to Severn Crossing Plc for repairs to the Old Severn Bridge despite tolls to cross both Severn Crossings currently stand at £5.50 for a car, £10.90 for a van and £16.40 for a bus or heavy goods vehicle.

It is hoped the committee will report back with recommendations for the government by the end of 2010.
