The Waitaki bridges in South Canterbury have been re-opened on Thursday following strength-testing.
The two single-lane bridges had been closed for a week because of flood damage.
The closure meant drivers had to make lengthy detours and access was cut between Hakataramea and Kurow.
Transport Agency area manager Colin Hey says strength-testing and visual inspections of all piers have confirmed that the bridges can safely reopen for use by all vehicles.
