The bus operator is alerting customers to route diversions and bus stop changes being put in place across the city ahead of Wales vs Ireland at the Principality Stadium from 11am until 6.30pm this Saturday.
Services 1 and 2 will continue to serve Canal Street in the city centre during the rugby road closures.
Bus stop changes will see the Baycar (service 6) starting from Customhouse Street and it will not serve the rear of Central Station or the city centre/Cathays Park loop during the road closure.
The 8, 9, and 9A to Cardiff Bay and the Sports Village; the 13 to the Sports Village, the 54 to Channel
View, and the X45 to Cardiff Bay Asda will all start from Hayes Bridge Road.
57, 58, and 61 to Pengam Green will start from Churchill Way. While the 13 to Drope; 15, 17, 18, 25, 61 to Pentrebane; 63, 64, 65, 66, 95 to Barry, and the 95A, 95B, 96, 96A, X91 will begin at Tudor Street.
The 21, 23, 24, 27, 28, 28A, 28B, 30, 35, 53, 54 to Cyncoed; and the 86 and 95 to Heath Hospital will all start from Greyfriars Road. Finally, services 92, 93, and 94 will start at Customhouse Street.
Lower St Mary Street will remain closed after 6.30pm, so buses will start to follow their Saturday night diversion in and out of the city centre earlier at 6.30pm instead of 10pm.
The X59 (Park & Ride East at Pentwyn) will also start and end on Dumfries Place all day on Saturday.
