M1 Widening J29-42 (Chesterfield-Leeds)

Scheme outline

This scheme proposed on-line widening of the M1 between Chesterfield and the M62 (junctions 29 to 42) to dual-four lane standard. From Chesterfield to the M18 and between Wakefield and the M62 the route would be fully upgraded to dual-four lane with full hard shoulders. The remainder of the route (including the whole section through Sheffield) would be widened to dual four-lane without hard shoulders, but with a wide hard-strip and emergency refuges every kilometre. Advanced signal gantries would also be installed.

The question of what would happen at the Tinsley Viaduct was unclear; the most likely solution would have been a lane drop at each end with just three lanes across junction 34.

The earliest phase of this work, to widen the section between junctions 31 and 32 which suffered serious problems with weaving traffic between the two interchanges, was completed. The remainder of the works were then cancelled in favour of three Smart Motorway schemes that would provide limited additional capacity at a reduced cost.

This scheme was completed in and we're no longer accepting updates or changes to this page.

14 January 2007

Start of work on the widening from J31-32 (Chesterfield to M18). This will provide a fourth lane between these junctions. It is a small-scale improvement in advance of the main work beginning in 2011.

14 March 2008

Work on widening the motorway between J31 and J32 is now complete. The next phase of work will start in several years and so this project's status is now 'in planning' once again.

Funding to widen the section between junctions 32 and 35a was confirmed in a statement by the Transport Secretary yesterday.
