Balfour Beatty has announced that temporary traffic lights will be in effect in Spitfire Link as the contractors continue building their compound, which will be used during the work on Junction 9.
The temporary two-way traffic lights will be in operation after peak traffic time, between 9am and 4pm, on Friday, January 17 and Monday, January 20.
Balfour Beatty will also be carrying out vegetation removal along the M3 near junction 9, which will require overnight closures of the southbound exit slip road on Thursday, January 23 and Friday, January 24.

A diversion will be in place, with motorists asked to continue along the M3 southbound to junction 11, exit and re-enter the M3 at junction 11 northbound, continue northbound to junction 9 to exit the M3.
The overnight closures will start from 8pm and finish by 6am, although this is subject to change depending on the volume of traffic and if the road can be closed safely.
A Balfour Beatty spokesperson said: “We advise you not to use a Satnav when following any of our diversions because there is a risk it could direct you down an unsuitable road or back onto our network when it is closed.”
The Junction 9 scheme is expected to cost between £190-220 million.
