M3 junctions 3 to 4 air quality mitigation: 60 mph speed limit
Proposals to implement a maximum 60 mph speed limit operating from 7 am to 7pm between junctions 3 to 4 of the M3 motorway
Last fetched 03 May 2026 · gov.uk
Detail
Proposals for implementing a maximum 60 mph speed limit operating from 7 am to 7 pm for approximately 3 miles between junctions 3 to 4 of the M3 motorway. This would tackle air quality issues due to higher levels of nitrogen dioxide pollution arising from the conversion of the hard shoulder into a running lane, particularly at peak times.
The consultation is aimed at affected stakeholder groups or individuals.
