Traffic chaos as fatality closes Melbourne's West Gate Bridge

One person has died in a horror crash between a motorcycle and a truck in Port Melbourne, leading to the closure of inbound lanes on Melbourne's West Gate Bridge on Monday morning.

The crash happened on the West Gate Freeway shortly before 8am. The truck driver wasn't injured in the crash.

The West Gate Bridge was reopened after being closed for more than four hours.

To add to the traffic chaos Monday morning, a truck also rolled over near Dock Link Road in West Melbourne, trapping the driver inside.

The Dock Link incident blocked two lanes and Ambulance Victoria confirmed they treated the driver for minor injuries.

Victoria Police asked motorists to avoid the area and seek an alternative route.
