Latest News

Despite challenges, the works for the disused subway infill at New Road and Kings Way was completed on time at the beginning of April.


At this time construction work is exempt from the latest Government guidance. We are currently working to ensure essential maintenance works are prioritised. This is an evolving situation, for the latest information please follow the council coronavirus updates.

Project Details

Work has been programmed to infill a disused subway on the island between Kingsway and the slip road leading to New Road, the project will start on Monday 2 March and will take up to 5 weeks. To undertake the work will require the closure of the slip lane from Kingsway to New Road for the duration of the 5 weeks.

This subway leads to a dead end and has attracted some anti-social behaviour. Stopping up the subway will allow us to remove the temporary security fencing and allow the council to plant trees/vegetation on this island, as part of its commitment to a green Southampton.
