Judgement Day: Cardiff travel warning for rugby double-header
Roads in Cardiff city centre have reopened to traffic as Judgement Day returned to the capital.
Ticketholders were searched at the stadium as part of enhanced security.
A full city centre road closure was put in place from 12:30 BST until 20:30 and there were extra trains on some services to carry fans into the city.
Arriva Trains Wales advised fans to arrive three hours before the event.
A spokesman said extra capacity would be added where possible. A post-match crowd management system was in place at both Cardiff Central and Queen Street stations.
Network Rail said there was planned engineering work between Worcester and Gloucester, so bus replacement services would operate between Gloucester and Worcester Shrub Hill, including Cheltenham Spa, all weekend.
