New Speed Limits Set on Western Avenue (A48)
New speed limits are in place on Western Avenue (A48) to improve road safety and air quality on one of Cardiff's busiest roads.
A 30 mph limit - previously set at 40 mph - is now in place on Western Avenue in both directions between Ely Roundabout and Gabalfa Interchange.
Speed limits on the remaining stretch of Western Avenue have also been modified, with the following changes in place:
- Travelling eastbound from the Gabalfa Roundabout towards Newport the speed limit is 50mph until the Llanedeyrn Roundabout - the speed limit on this stretch of road was previously set at 70 mph. The speed limit to the east of Llanedeyrn Roundabout remains at 50mph, increasing to 70mph on the approach the A48(M) and the M4.
- Travelling westbound from Llanedeyrn Roundabout towards Gabalfa Interchange the speed limit is 50mph, until the University Hospital of Wales where the speed limit reduces to 40mph, which remains unchanged. From the Gabalfa Roundabout, drivers enter the 30mph limit until the Ely Roundabout.
All the new speed limit signs have been installed on Western Avenue (A48) and the new speed limits are live and can be legally enforced.
