SPEED cameras have been set up on the M4 while work on a new southern access road continues.

The embankment south of the motorway near Wichelstowe is part of a major scheme to create a new tunnel underneath the M4 without needing to close the busy highway.

A Swindon Borough Council spokesman said: "You may have noticed average speed cameras have been installed on the M4, which will be in operation within the next two months.

"When in operation, the M4 will be reduced to a 50mph limit affecting a short distance of road to protect workers and drivers.

"The Southern Access, will create an additional route into Wichelstowe under the M4 will help to support 4,500 new homes, the new district centre and will also unlock 12.5 hectares of employment land.

"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."
