Slow traffic and one lane is closed on the M3 southbound between junction 11 at Winchester and junction 12 at Eastleigh following an accident involving four cars.
Drivers face major disruption this weekend as the M3 is closed from this evening.
It's to allow for a bridge to be demolished between junctions two and three as part of smart motorway scheme to convert the hard shoulder into a running lane.
The work was due to end next month but is now going to run another six months.
It comes as plans to upgrade the M4 will go ahead with work starting next March along with five years of chaos.
Critics say the schemes are not safe.
