Looks like the dedicated lanes for turning left approaching from Cathays Terrace and Fairoak Road and for turning right approaching from Crwys Road and Whitchurch Road have been removed.

This means that half as much traffic can enter the junction, so there are long queues of idling vehicles in all directions at busy times.

I walk past there twice every day and I reckon that it's already had a negative effect on the air quality in the area.

Brilliant work by the council.
