A council meeting last night confirmed the council’s decision to promote the Transport and Works Act application for the Mersey Gateway Project.
Included in the discussions was the cost of the project, which has rise by 11 per cent to £431 million.
The increase of £41million has been caused by changes to the design.
It specifically includes changes made to the existing roadway along the Central Expressway, including environmental works such as noise barriers, replacement footbridges and landscaping works, along with additional works to deal with contaminated land in south Widnes.
The funding agreement already in place with government is sufficient to cover the cost increase.
The endorsement of the full council follows last months decision from Halton’s Development Control Committee to refer three linked planning applications that allowed the project to proceed to the Secretary of State.
