Motorists travelling on the M3 motorway today, Monday, September 28, 2026, are being urged to check the latest traffic information before setting out, with planned roadworks and closures potentially affecting journeys.
At the time of the latest official update, National Highways' daily closures information was updated at 1:15pm on September 28. The agency warns that road closures can change at short notice, particularly because of changing traffic and weather conditions.
Drivers should also be aware of overnight work affecting nearby routes. National Highways has confirmed an overnight M27 westbound full closure at Junction 4, running from September 28 to October 21 on Monday-to-Friday nights between 9pm and 6am. The published diversion route uses the M3 northbound towards Junction 13 before returning via the M3 southbound.
The M3 is a major route connecting London with Hampshire and the south coast, meaning incidents or planned closures can quickly affect surrounding roads.
There have been reports of M3 incidents in recent days, but motorists should distinguish between confirmed accidents, congestion and scheduled roadworks when checking online traffic reports.
Drivers heading through areas including Winchester, Basingstoke and Southampton should allow additional travel time and monitor live traffic information before and during their journey.
Motorists are advised not to rely on social-media reports alone for information about an alleged M3 crash. Official National Highways updates remain the best source for confirmed closures, major incidents and diversions.
