Highways England will introduce a new speed limit of 60mph between Junctions 1-3 on the M602 at the end of September in a bid to cut air pollution in this area which is now at dangerously high levels.
Junction 1 is the Eccles Interchange, Junction 2 is the Gilda Brook Roundabout and Junction 3 is the Regent Road Roundabout on the M602.
Nitrogen Dioxide released from car exhausts is a serious air pollutant and contributes to the warming of the planet. Air pollution is also linked to a wide range of serious illnesses and conditions. It contributes to the equivalent of 1,200 deaths a year in Greater Manchester.
Highways England says that research predicts that there will be a reduction in Nitrogen Dioxide when traffic speed is reduced from 70 to 60mph. The speed limits will be operational 24 hours a day. The reduced speed limits will be assessed after 12 months to understand the impact on air quality levels.
Drivers will see new signs on the network making clear that the speed limit is at 60mph to improve air quality.
