Interserve has been tasked with building two new roundabouts on the A140, one to the north and one to the south of Eye Airfield in Brome.
A new link road will be constructed between the north roundabout with a priority junction on the B1077 between Brome and Eye.
The scheme, when complete, will provide improved access from the existing A140 to the old airfield site which is being re-developed as the Mid-Suffolk Business Park.
Interserve Construction expects to start work shortly with completion expected by the end of the year.
The contract was awarded through the the Eastern Highways Alliance Framework 2 and is the second highways contract secured by Interserve this month through that framework. Earlier this week we reported that Hertfordshire County Council has given it a £15.6m contract to upgrade a section of the A602 between Watton-At-Stone and Tonwell.
