Warrington Borough Council has confirmed the closure through the publication of a Road Traffic Regulation Act 1984 notice.
This puts in place a prohibition of driving and footway closure for Peace Drive, outside the Peace Centre and St Gregory’s Catholic High School in Great Sankey.
The order will be effective from January 31 for a period of 18 months, with access under the control of the relevant contractor for the duration of the works.
The alternative route for the footway closure will be via Sankey Way, Cromwell Avenue and vice versa.
A council spokesman said: “The restrictions are required to allow for the refurbishment of the Peace Centre.”
As previously reported, sections of the iconic Peace Centre are to be transformed for special educational needs (SEN) use.
Plans have been approved for the changes to create a provision of a post-16 and post-19 educational facility within the existing Peace Centre building, including classrooms and multi-purpose spaces.
External facilities to be provided include an all-weather walking track, horticultural learning area and playground, as well as car parking for minibuses and an enlarged pick-up and drop-off space.
The Tim Parry Johnathan Ball Peace Foundation, set up after the IRA bombing of Warrington in 1993, which took the lives of Tim Parry, aged 12, and Johnathan Ball, aged three, will continue to occupy space within the building for office use a multi-use space for occasional activities.
The project also includes the expansion of the existing staff parking provision of St Gregory’s High School car park and the provision of a safe drop-off and pick-up area, together with a turning circle along Peace Drive.
