M1 J19-16 Smart Motorway

Scheme outline

Upgrade of the M1 to provide Smart Motorway technology between Junction 16 (Kislingbury) and 19 (Catthorpe), with the stated aim of improving traffic flow, reducing congestion and increasing safety.

The upgraded section will operate All Lane Running, converting the hard shoulder to a permanent running lane. This will provide four lanes in each direction on this section of the M1, with emergency lay-bys to replace the hard shoulder.

Work to upgrade the central reservation to a concrete step barrier on this section was completed at the end of 2015, in anticipation for the commencement of these works. Due to the level of disruption these initial works caused, Highways England has decided to roll out the Smart Motorway work in two phases, to minimise driver frustration, which is compounded by the nearby J19 Catthorpe Interchange improvement works. Work will begin between junctions 16 and 17 first, with work between junctions 17 and 19 beginning afterwards, when the Catthorpe Interchange works are completed at the end of 2016.
