Operating company Amey is resurfacing the northbound carriageway.
Restrictions and the contraflow came into force on Saturday morning and will continue until midnight on Sunday.
The northbound off-slip at junction 3 is also closed. A diversion route for traffic which would normally use that exit is signposted from junction 2 Pitreavie interchange via the A823(M), the A823 Queensferry Road and the A907 Halbeath Road.
Police Scotland advised motorists planning to use the motorway to allow extra time for their journey.
