The Highways Agency will start refurbishing traffic signals on the A5 at Walkmill Lane, Cannock next week.
The work will take place overnight between 7pm and 6am and will take approximately one week to complete.
While the work is underway there will be temporary traffic lights in operation at this location and there will also be some side road closures and local traffic diversions in place. All closures will be signed in advance and a clearly signposted diversion route will be in place.
Highways Agency project manager, Purnima Kaul, said: “These essential works have been planned carefully to minimise disruption for motorists”
