The Department for Transport is to provide extra funding to widen the Crediton Link Road in Devon.
The County Council has been given nearly £3,000 towards the scheme which should start in July.
In total the scheme will cost more than £10,000 and be finished in November 2014.
The money will also be spent on a cycle and footway between A377 and the Lords Meadow Industrial Estate.
A multi-million pound link road for Camborne, Pool and Redruth has been approved by the Department for Transport.
The department has said it will contribute £16 million towards the £27 million cost. Cornwall Council has also been allowed to use compulsory purchase orders for the route.
It will create 6000 jobs and more than 7000 new homes. Work could start in the spring.
