Reduced speed limits are crucial to the upgrades of the network to protect road users and reduce the possibility of an accident.
National Highways clarified that there would be additional Traffic Officer patrols when upgrades are taking place.
The transport organisation added that it keeps drivers updated with the latest traffic news on social media and its website.
At present, drivers are being warned of two serious traffic issues, with motorists dealing with delays and diversion routes.
