DRAFT regulations to vary speed limits on the M1 in South Yorkshire have been published for consultation - as part of a planned scheme to create an extra fourth lane.
Work is due to start on the project early in the new year, widening the motorway for 10-and-a-half miles between junctions 32 and 35a.
The hard shoulder will be converted into a new lane and the scheme is expected to be completed by summer 2015.
The temporary reduced speed limits will seek to manage traffic speeds and help reduce congestion.
Introducing the speed limits requires new regulations, so draft regulations have been published as part of an eight week consultation which finishes on February 11.
Before any work starts, public information exhibitions will be held.
