Lancashire County Council said it still intends work on the Heysham M6 Link Road in July, despite an appeal that could result in a Judicial Review.
Campaign group Transport Solutions for Lancaster and Morecambe (TSLM) announced it had launched an appeal against the Secretary of State’s decision to grant permission for the £123m road.
The group’s chairman David Gate said that not only was the link road the wrong solution to the district’s transport problems, but that, according to legal advice, the decision was also wrong in law.
The link road’s project manager Steve McCreesh said the county council was “very disappointed” with the decision to appeal, as it would delay the project and increase costs.
Mr McCreesh said the project would only be delayed if the appeal was accepted and the decision was put up for Judicial Review.
A county council spokesman said that it had given provision in its timetable for an appeal process to take place.
The Department for Transport did not wish to comment at this stage on the appeal.
