M1 managed motorway £150m plans on public view
Plans for a length of the M1 in South Yorkshire that carries 110,000 vehicles a day to become a managed motorway are to go on show in Sheffield.
The work will cost £150m and reduce congestion on almost 11 miles of motorway said the Highways Agency.
The motorway's hard shoulder will be converted to a permanent traffic lane from junction 32 to 35a.
Plans for a managed motorway on the M1 from junction 39 to 42 in West Yorkshire will be on show in February.
Mandatory speed limits
The plans for the motorway near Sheffield include variable mandatory speed limits displayed on overhead and verge-mounted signs to smooth traffic flow and reduce congestion said the agency.
Work on this scheme is due to start later this year and be operational in 2015.
A project to upgrade the M62 between junctions 25 and 30 in West Yorkshire is currently under way and still has about a year to run.
The first hard shoulder running scheme was introduced on the M42 in the West Midlands in 2006.
The exhibition for the South Yorkshire scheme will be held at The Source conference centre, in Meadowhall Way, Sheffield during Friday and Saturday.
An exhibition on the West Yorkshire scheme will be held in Wakefield in February.
