Upgrade of the M1 between junctions 28 (Pinxton) and 31 (Aston) to Smart Motorway. This will involve installation of electronic equipment to enable the use of variable speed limits and the installation of emergency refuge areas. It will also see the hard shoulder converted into a fourth permanent running lane. The completed motorway will not have a hard shoulder.
The scheme also includes the replacement of the central barrier with a new continuous concrete barrier. This part of the works has caused some delays, with parts of the new concrete barrier replaced due to defects in the original work.
This scheme, along with a number of other Smart Motorway schemes, replaces earlier proposals to conventionally widen the M1 to dual four-lane motorway between junctions 28 and 42.
This scheme was completed in and we're no longer accepting updates or changes to this page.
Between junctions 28 and 31 all central reserve work is done, emergency lay-bys now being constructed, and some of the new matrix signs have gone up.
Due to problems with the concrete, the new central barrier is now being replaced, but HE still claim completion for end 2015.
All the cones have gone from around J31, and the temporary speed limit has been lifted.
J29a-31 has a 'temporary layout', no cones, 70mph speed limit but only 3 lanes marked out, no hard shoulder running and no working gantry signs. Exactly as it was before the work started!
There is now four lane running with no speed restrictions - appears that work is complete.
