New speed cameras will go live on a stretch of the M4 in Newport later this month, the Welsh Government has confirmed.
The new cameras are currently being installed between Junction 24 (Coldra) and Junction 28 (Tredegar Park) and will begin operating on March 15.
The speed cameras are part of a new "50mph Average Speed Enforcement" system planned to improve congestion in the area.
Work to install the cameras began on Monday, with closures planned to be taking place between J24 and J28 over the next two weeks.
The stretch of road will be closed in the eastbound direction between March 1 and March 5, and westbound between March 8 and March 12.
The closures will be in place overnight, between 8pm and 6am the following morning.
The Welsh Government has stated that the speed cameras are then expected to be in place and operational by Monday, March 15.
Obviously the current queues at the Brynglas Tunnels aren't long enough!!!!!!
