The unusual reason why average speed cameras could be installed on this road
Average speed cameras could be installed on a busy stretch of road in a bid to deter speeding motorists and tackle pollution levels.
The Welsh Government has announced that discussions are being held over whether average cameras should be installed on the A494 in Deeside in a bid to deter drivers breaching the speed limit.
It comes after the speed limit was temporarily reduced from 70mph to 50mph along a stretch of the road in a bid to reduce pollution.
Tests had found that levels of nitrogen dioxide being emitted were above legal limits.
But since the speed reduction has come into force, many motorists have complained that other drivers are continually flouting the new speed restrictions.
The measures were introduced in the hope that the restrictions would have a “smoothing” impact on traffic, with vehicles driving at around the same speed of between 40mph and 50mph.
Research has indicated that nitrogen dioxide levels are at their lowest when cars are travelling at this speed, the Welsh Government said.
A report had previously recommended that average speed cameras could help with the reduction of pollution on the stretch of road, and the Welsh Government have confirmed that idea is still being considered.
A spokesman said: “The 50mph speed limit on a section of the A494 has been implemented to reduce nitrogen dioxide levels which are currently above legal limits.
“Enforcement is currently approached in the same way as other speed limits on the trunk road network.
“However, Welsh Government officials are continuing discussions with the police and GoSafe about the most appropriate method of enforcement going forward including the possibility of installing average speed cameras to help ensure 24 hour a day compliance.”
The Welsh Government has not said whether the 50mph limit will become permanent in future.
They have said that the temporary limits, which were also introduced on a stretch of the A483 in Wrexham, will be in place until the roadside monitoring has established the effectiveness of the limits.
