UPDATE: 6:23pm Macquarie Pass has re -opened.
The Illawarra Highway is closed in both directions on Macquarie Pass due to an oil spill.
Light vehicles can use Jamberoo Mountain Road instead, and should allow extra travel time.
Heavy vehicles need to go via the Hume Motorway, Picton Road and the M1 Princes Motorway, adding at least 30 minutes to the trip.
Crews are currently in the process of cleaning up the spill.
