TRUCKERS' groups have stepped up efforts to get the M62 widened to eight lanes.
The Freight Transport Association and Road Haulage Association wants England's congested motorway network to be given an extra lane in each direction.
The AA, RAC and British Chamber of Commerce are also backing the call.
A spokesman for the Freight Transport Association (FTA) said: "By widening an existing road you cut out a good deal of the pain of building a new road."
He added: "It's a relatively economic means of generating more capacity."
He argued that widening a road by 24 feet could slash the estimated £20 billion lost every year to the British economy through traffic jams and delays.
"One lane on either side will make a fundamental difference," added the spokesman.
Transport Secretary Alistair Darling is drawing up a 10-year plan for the national road system and is about to agree transport spending.
Investment in the railways is to increase 48 per cent over the next five years.
The FTA spokesman added: "There's a lot of money going into rail investment. We argue there should be a lot of money going into road investment."
