Sean McCallion, Operations Director, Danaher & Walsh Civil Engineering Ltd, said: “We are delighted to have been awarded this contract and look forward to working collaboratively with Galliford Try and Leicestershire County Council to deliver a distributor road around Melton Mowbray and therefore a more pleasant environment in the town centre for the community to enjoy.
“Along with Galliford Try we will be working with key stakeholders within the community to ensure minimum disruption and maximum benefit to local people, as a result of the works.”
