Work is ongoing on construction of the M4 Smart motorway between junctions 3 and 12.
This is the longest smart motorway project in England to date (51km, 32 miles). To minimise disruption work will take place on different stages at different times.
Main aspects of the scheme are as follows:
- Use of the latest technology to monitor traffic flow and set speed limits accordingly in order to keep traffic moving smoothly
- Information about road conditions and speed limits will be displayed on electronic road signs
- The hard shoulder will be converted to a permanent traffic lane to create additional capacity.
