The M27 motorway in Hampshire has reopened for the first time in over two years, following a multi-million-pound project to reduce noise, improve drainage, and strengthen the central reservation. However, drivers are now facing a temporary 50mph speed limit as final testing continues.
Project Details
National Highways has been carrying out works on the M27 between junctions five (Eastleigh) and seven (Hedge End). The project aimed to address noise concerns, enhance drainage systems, and reinforce the central reservation for improved safety.
Hampshire County Council leader Nick Adams-King described the reopening as "good news" after what had been a "very long stretch of cones and lane closures." He added that removing the lane closures would be a "welcome relief for everyone who uses this section of motorway" and expressed hope that spring would indeed bring the removal of the temporary limit.
Testing and Speed Limit
National Highways stated: "We expect to complete the first stage of technology testing on 21 April 2026, and lane closures will be removed from both carriageways by 06:00 that morning. A temporary 50mph speed limit will remain in place while we do the final stage of testing and recommissioning with all lanes open. We'll remove this temporary limit once all testing is complete later in the spring."
Adams-King humorously noted that "later in the spring" in roadworks terms has been known to drift into July, but welcomed the progress nonetheless.
Understanding National Speed Limits
For cars, the national speed limit is typically 70mph on motorways and dual carriageways, and 60mph on single carriageways. The national speed limit sign is a white circle with a single black diagonal stripe. In built-up areas, the limit is 30mph, indicated by a red circle with the number 30.
Speed limits are enforced by fixed cameras or temporary camera vans in speeding hotspots. Serious offences can lead to court appearances, hefty fines, or driving bans.
