There was heavy traffic on a major road in Cardiff after a crash and flooding on Saturday. The A4232 northbound exit slip road was closed due to flooding at A48 Cowbridge Road (Culverhouse Cross), according to traffic monitoring service Inrix.
There was a crash on the Culverhouse Cross roundabout which exacerbated congestion and two lanes were partially blocked. Traffic built on the A4232 with queues stretching beyond Michaelston-super-Ely.
Bus company Adventure Travel said in a post on X, formerly known as Twitter, that its C1 service was experiencing delays due to the collision at the roundabout but added it was not involved in the incident.
Emergency services attended the scene of the crash. South Wales Police said it had been called to a two-vehicle collision at the roundabout at around 9.30am. There were no serious injuries. The exit slip road re-opened at around 12.30pm and all congestion along the road had eased by around 1pm.
