[holding answer 19 November 2007]: Work to widen the M1 between J25 and J28 began with site clearance on 29 October 2007, with the main start of works in January 2008.
Further planning for the remaining sections of the M1 between J21 and J30 is being undertaken and a programme is being developed. Subject to satisfactory completion of the necessary statutory processes, I hope to be able to make an announcement about this next year.
The M1 from J25, to part way between J27 and J28 is already lit and replacement will be included as part of the widening.
Designs of the lighting have not yet been finalised for the remaining sections of the M1. The intention at this time it to follow current guidelines; which includes economic assessment, to assess the lighting need on a location by location basis.
