A NEW central reservation is to be fitted to a stretch of the M1 which will see a temporary speed limit of 50 MPH in place.

The work will be between junctions 37 and 38 and will see the Highways Agency replace the existing steel barrier with concrete to reduce the risk of vehicles involved in accidents from crossing sides of the motorway.

Work will start on October 15 and is due to last until December 21.

Three narrowed lanes will be in operation during the day but there may be lane closures overnight.
