Part of Portobello Rd, at Burns Point, Dunedin, was closed for about 20 minutes this morning after a car hit a crash barrier on the harbour side at 7.35am.
It is understood that no-one was seriously hurt in the solo-vehicle crash, at Vauxhall, a police spokesman said.
Police inquiries are continuing.
Police are also investigating an earlier incident in which a car rolled over on the Crawford St overbridge at 1.25am today.
An ambulance attended, but it is understood that no-one was seriously hurt in this crash, which also involved only one car.
