There have been calls for safety measures to be put in place after a lorry got stuck under a bridge near Bangor.
It's the second such incident at the bridge this year.
Shortly before 9am on Friday, a lorry crashed into the bridge on the Ballysallagh Road between Bangor and Dundondald.
The vehicle was stuck for several hours, causing traffic chaos, with a nearby rail line also affected.
The structure received only minimal damage and the driver was uninjured.
In 2017 the road was closed for several weeks after the bridge - which is 3.4m high - was damaged after being hit by a lorry.
Since signs was posted around the bridge warning of its height. In January this year it was again hit by a lorry.
Alliance councillor Gillian Greer said more needs to be done to prevent crashes. He said if action is not taken, "we will be back here in the future".
“This is a busy road used regularly by commuters, however, this is far from the first time it has been closed either fully or partially following a lorry colliding with the bridge. That has a major impact on drivers, causing extra congestion, and on nearby businesses, hitting the local economy," she said.
“Alliance has repeatedly spoken to the Department for Infrastructure to request further safety measures along this route. As evidenced by today’s incident, it is clear the current set-up is not enough.
"The common sense approach would be for a form of barrier at the approaches to the bridge, to allow drivers to realise their vehicle is too tall to pass under it."
