Work to build the embankment south of the M4 is progressing well.
The embankment will play a major part in how we will create a tunnel under the M4 without closing the road. We will be explaining how this will work in future editions.
You may have noticed that average speed cameras have been installed on the M4, which will be in operation within the next two months. The M4 will be reduced to a 50mph limit affecting a short distance of road to protect workers and drivers.
