Call for improved transport links across Warwickshire
Better roads and railways are needed across Warwickshire as well as planned improvements to the M6, according to the county's chamber of commerce.
The M6 in Warwickshire will become a managed motorway between junctions two and four as part of the government's £28bn plan for Britain's roads.
It means the hard shoulder will be used as an extra lane during peak times.
The chamber's vice president Peter Burns said the expected improvements did not go far enough.
"We are [happy] but we have to look at it with a degree of caution," he said.
"Anything that's going to improve traffic flow's going to be good."
Mr Burns said he hoped the managed motorway system would work as successfully on the M6 as it had on the nearby M42, but added that one more lane was not "necessarily going to be the answer".
"Whether you then build additional roads, whether you then do better things with the railways, there's a whole load of things needs to happen," he said.
