A truck is wedged on two wheels beneath a Melbourne rail bridge causing morning traffic peak delays.
City Road in South Melbourne was partly closed to traffic after the crash on Tuesday.
"We've had another truck strike a rail bridge and I mean really strike," VicRoads spokesman Chris Miller told 3AW radio.
"Hit it so hard he's ended up with only two wheels on the ground so he's wedged in the air."
A photo from the scene shows the truck's cabin smashed against a pylon and the driver's side in the air beneath the bridge.
A "clearance 3.8m" sign is attached to the bridge.
Traffic management services were anticipating a lengthy recovery effort.
