The government is reportedly planning to agree to a new toll road on the M4 in South Wales, but this is part of a multibillion-pound scheme of road upgrades in the UK.
According to the Times, the other upgrades include:
- A1 between Newcastle and Berwick-Upon-Tweed to be converted to a dual carriageway
- Widening of the A47 in Norfolk
- A303 to be turned into a continuous dual-carriageway
