Background

An average of approximately 28,000 to 30,000 motor vehicles use this section of the A11 daily, with around 2,000 to 2,500 heavy goods vehicles (HGVs) travelling southbound daily.

These figures are significantly higher than average for an A-road in England. 

Keeping the road well maintained helps improve freight movement, supply chains, and road user journeys.

This scheme will help the A11 cope with traffic levels and stay well maintained. Once complete, drivers will benefit from a better defined and safer road surface.
