Roads minister Robert Goodwill said today that motorway schemes, like the one used to relieve traffic on the M6 in the Midlands, could be rolled out "more and more across the country".
Speaking to ITV News Central he said: "The main thing is to keep the traffic flowing and this system does keep the traffic flowing, it's much cheaper than having to put extra lanes on motorways."
He added: "Over the next 15 years we are going to invest £50 billion in road schemes."
