A person has died after a truck collided with a car in one of two crashes on the Princess Freeway this morning.

The Princes Freeway was completely closed out-bound and partly closed in-bound after two crashes in close proximity within less than two hours of each other.

In the most serious smash, there was a collision soon before the Kororoit Creek Road out-bound exit ramp between a truck and car.

All out-bound lanes of the Princes Freeway were finally reopened just before 2.45pm, nine hours after the collision.

All outbound lanes of the Princes Freeway, Altona North are now open following an earlier serious collision near Kororoit Creek Road. Some delays remain, however they are expected to ease quickly. Thank you for your patience. #victraffic pic.twitter.com/GwGonPtdSK

Meanwhile, there was a second crash between two cars Melbourne-bound, that caused the closure of a middle lane.
