Two people have been injured after a trailer came off a car on a Hawke's Bay bridge, smashing into a vehicle travelling in the opposite direction.
The freak crash on State Highway 2 near the Tutaekuri River Bridge was reported to police at 11.20am, a police spokesman said.
A trailer from a car travelling north had detached, and had smashed into another vehicle travelling south over the bridge, he said.
A guard rail of the bridge was also damaged during the incident.
The southbound lane has been closed with traffic diverted down Meeanee Rd, while the northbound lane is open.
A spokesperson for St John said paramedics treated one patient in a moderate condition and another with minor injuries and transported them both to Hawke's Bay Hospital.
