Public planning inquiries into the Lincoln Eastern Bypass and East-West Link Road have come as a little surprise, says the politician in charge of highways at Lincolnshire County Council.
Both reviews are set to take place in February and March next year. A planning inspector will consider objections before final decisions on the schemes are made.
Councillor Richard Davies, executive member for highways, said: "As we expected there has been a lot of interest in both the Lincoln Eastern Bypass and East-West Link Road.
“Projects of this scale often involve public inquiries and we very much welcome the interest of the local community and I hope that their concerns can be properly addressed.
"I can't pre-empt the recommendations or duration of an inquiry, but we expected that there would be one and have built extra time into the project schedule to allow for this."
The start date for the East-West Link Road between Tritton Road and Pelham Bridge via Tentercroft Street is August 2014, with work on the bypass set to begin in late 2014.
