TRAFFIC will not be allowed to travel on the new temporary road standing in for the A591.

Highway engineers do not think the temporary road could be opened to two-way traffic without causing gridlock and two hours of queues at each end.

On average, around 5,000 vehicles travel on the A591 a day in the months of March, April and May. 

Given this likely volume of traffic and the narrowness of the road, highway engineers have decided the temporary road should not be opened to more vehicles. 

School buses, scheduled buses, emergency services and gritters will still be able to use the temporary road. 

The road will also be open to walkers, cyclists, residents living between the north and south road closure points on the A591 and essential construction traffic and site operational vehicles.
