After a four-year trial to assess the impact on air quality, the 60mph speed limit on a key stretch of the M602 in Greater Manchester is set to be lifted. The trial, which began in September 2020, aimed to determine whether reduced speeds would lead to lower emissions around Salford and Manchester.
National Highways has reported that the trial along the four-mile section of the motorway, linking Regent Road in the city centre with the M60 outer ring road, indicated improvements in nitrogen dioxide levels, achieving compliance with air quality standards.
A recent report by the Greater Manchester Combined Authority (GMCA) noted that National Highways informed Transport for Greater Manchester in July about the removal of the temporary speed limit on the M602 between junctions 1 to 3 Eccles.

Confirming the decision, a spokesperson for National Highways stated: "The M602 trial between junctions 1 and 3 has been completed."
They added, "The speed limit will now return to 70mph from 60mph. Work for this is underway and we are planning to remove all associated signage in the coming weeks", reports .
The spokesperson also mentioned that data compilation for the air quality report is ongoing and highlighted that the ultimate solution to air quality challenges lies with vehicle manufacturers and changes in vehicle use. In the meantime, National Highways will persist with its extensive research and innovative solutions.
"Air quality monitoring tubes will remain in place to provide a greater understanding of any impacts following the end of this trial."
The GMCA report suggested that the reduced speed limit on the M602 would be considered as part of the new clean air zone plan, which won't impose charges on drivers within Greater Manchester. The Mayor's office is favouring an 'investment-led approach' over a city centre congestion charge, with the aim of accelerating the improvement of air quality.
