M1 overnight closures as part of £373m smart motorway scheme
The M1 will be closed overnight for two weeks as part of a £373m smart motorway scheme.
There will be full overnight closures in each direction between Junction 14 (Milton Keynes) and Junction 15 (Northampton), beginning with the southbound carriageway on Monday, September 6.
The road will be closed from 9pm-5am each night until Monday, September 20, when the northbound carriageway will then be shut.
The second closure will take place from 10pm-6am each day for another 14 nights.
The work is part of the conversion of the M1 into an ‘all lane running’ smart motorway, which will remove the hard shoulder and turn it into a running lane.
On ALR smart motorways, lane one (formerly the hard shoulder) is only closed to traffic in the event of an incident – this is indicated by a red X on an overhead sign.
A statement from National Highways on the project states: “We need to close some junctions in order to progress our work.
“These closures are required for traffic sensors as part of our Motorway Incident Detection Automatic Signalling system.
“This detects the levels of traffic and provides real-time information to our regional control room staff who monitor the traffic conditions and safety.
“The data also automatically sets and adjusts the variable traffic speed limits shown on the motorway message signs to drivers.
“It keeps traffic moving smoothly, reduces congestion, makes journey times more reliable, and helps reduce accidents.”
The works between Milton Keynes and Northampton are part of the overall improvement to a 23-mile stretch of the M1 between Junction 13 (Brogborough) and Junction 16 (Daventry).
