It's been a rough morning for Sydney commuters following a truck crash on the M5.
The incident happened just before 6am, however there remains a seven-kilometre backlog of traffic after 10.30am.
One of three westbound lanes remains closed, while eastbound traffic has returned to normal.
The three-vehicle crash happened at Revesby in Sydney's south-west, with a truck rolling while trying to avoid the incident near Beaconsfield Street.
This closed two of three westbound lanes, with eastbound traffic banked back to the M5/M7 interchange.
