Information from FM Conway. "We are planning a southbound carriageway closure between Bobbing Interchange and Stockbury roundabout on 11 April 2022. We are undertaking litter picking to the on slips at Key Street and Bobbing as well as working in the centre reservation. Hours of work will be 20:00 – 06:00hrs, although we should be off around 01:00hrs. Lane 2 northbound will be closed to allow our operatives to work in the centre safely. We need to use a full closure to gain access to the on slips, we cannot use lane closures for these areas."
