Overview
- The M3 westbound between Junction 12 (Eastleigh) and Junction 13 (Southampton) was blocked by a collision on Sunday and emergency services remain at the scene.
- Live traffic feeds and eyewitnesses report a car and a motorcycle were involved and multiple ambulances and fire engines have attended.
- National Highways says current delays are about 40 minutes with roughly four miles of congestion stretching back to Junction 10 (Winchester).
- Drivers are queuing to a standstill and are using local routes through Twyford and around Eastleigh Train Station to avoid the blockage while the opposite carriageway is slowed by onlookers.
- Motorists should follow official diversion signs, consider leaving the M3 early at Junction 9 or 11, and check National Highways for further updates and clearance times.
