The programme for the improvement works to junction 28 of the M4 at Tredegar Park roundabout has been adjusted to avoid clashing with ongoing construction works on Newport Council's highway network associated with rail electrification. The works are now programmed to start in February 2017, subject to commercial agreements with the Contractor, Newport City Council and the Southern Distributor Road Concessionaire, Morgan Vinci Limited.
