Following Cardiff City’s home Championship match with Millwall at Cardiff City Stadium, gates will open at the Principality Stadium for Anthony Joshua’s world heavyweight title fight with Carlos Takam in front of a sell-out 75,000-strong crowd.
And with rail services to Cardiff affected by electrification work on the day, Highways England is anticipating increased traffic volumes at the Severn Crossings and on the strategic road network.
Gareth Price, south west emergency planning officer for Highways England, said:
We have placed roadside messages well in advance of the event but we would like to remind road users to plan ahead. Roads leading to Cardiff are likely to be busy, particularly the M4 westbound, M49 and M5.
Our aim is to keep the Highways England network running while keeping sports fans and other road users safe and informed, and on the day we advise people to check our traffic and travel information channels, set off early and allow plenty of time.
