Consultation opens on Welsh motorway air quality plan

The Welsh government has opened consultation on its final package of measures intended to bring air around motorways and trunk roads into compliance with air quality limits

The Welsh government has opened consultation on its final package of measures intended to bring air around motorways and trunk roads into compliance with air quality limits.

A series of temporary 50mph speed limits have already been implemented on the A494 at Deeside, A483 near Wrexham, M4 and at Port Talbot and Newport and A470 between Upper Boat and Pontypridd in June.

The consultation identifies a number of further actions that could be implemented at particular locations, among them air quality barriers, clean air zones, parking improvements, junction closure and variable diversions. These may be subject to ongoing review depending on the success of the 50mph zones in reaching the 40 micrograms per cubic metre limit for nitrogen dioxide.
