Work on the £96 million Lincoln bypass is expected to start this year after approval for the project was granted.
This follows a public inquiry which took place in August and the granting of legal orders from the Secretary of State.
The orders will allow the council to appoint a contractor and it is hoped that work will then be able to start on site later this year.
Lincolnshire County Council executive member for highways and transportation, councillor Richard Davies, said: “I am very pleased with the outcome of this inquiry. I am glad that the inspector saw that not only is the bypass a vital component in our plans to create a fit-for-purpose highways infrastructure for the needs of an expanding Lincoln. Hopefully we can now progress with this long-awaited bypass without any further needless expense or delay.”
