Proposals to introduce a 60mph speed limit on the M1 between South Yorkshire and Derbyshire are being opposed.
The Highways Agency wants to convert the hard shoulder into a fourth lane to widen an 18.5-mile stretch of motorway as part of a project to improve traffic flow and allow greater volumes to use the route.
A 60mph speed limit enforced by speed cameras has been proposed between 7am and 7pm to help reduce carbon emissions.
But Derbyshire County Council has objected to the proposals as part of a Highways Agency consultation after organisations including Derbyshire, Nottinghamshire and Leicestershire Chambers of Commerce Group raised concerns.
Councillor Dean Collins, Derbyshire County Council’s cabinet member for jobs, economy and transport, said: “Business organisations have told us they’re concerned about the message a blanket speed reduction sends out.
“We’re working hard to attract new businesses to the area and a lower limit will add to the perception that the M1 is overly congested. Other sections of the M1 have air quality management areas but do not have lower speed restrictions as a result, so we don’t see why they should be imposed in Derbyshire.
“This area of the county is open for business. It’s a great location to base your firm and we wouldn’t want businesses put off because they were given the wrong impression about this stretch of the motorway.”
