Motorists are being advised of temporary traffic lights in place, as highways work gets underway.
North Lincolnshire Council is investing £50,000 to improve the traffic lights at Britannia Corner and the junction of Deyne Avenue and Doncaster Road in Scunthorpe.
The traffic lights on Britannia Corner, which is the junction of Doncaster Road, Frodingham Road, High Street and Oswald Road, and the traffic lights at the junction of Deyne Avenue and Doncaster Road are being replaced.
The traffic lights currently in place require a lot of maintenance, therefore the new lights will reduce the amount of time needed to look after the lights and reduce the risk of the traffic signals failing.
Work started on August 1 and is expected to last five weeks.
Traffic at Britannia Corner will be controlled using temporary traffic signals using the current timings and phasing to minimise disruption between 22 August and 5 September.
The traffic lights at the Deyne Avenue, Doncaster Road and Lidl entrance will be turned off between 22 August and 5 September. Drivers will have to use this as a standard give way junction.
Councillor Neil Poole, cabinet member for Environment, said: “The traffic lights at these two busy Scunthorpe junctions are fairly old, which means a lot of time is spent maintaining them. By replacing the lights it will save time and money in the long run.
“The temporary traffic lights will be regularly monitored to reduce the impact on traffic and pedestrians whilst work is carried out.
“We apologise for any inconvenience caused but it is necessary for the lights to be replaced. Drivers are urged to drive with extra care at both of these junctions.”
