Drivers have voiced their anger after two sets of roadworks caused enormous traffic jams in Berwick over the weekend.
Part of the problem was the closure of the A1 Berwick bypass between Scremerston and East Ord for repairs.
However, the situation was exacerbated by roadworks on the Tweedmouth end of the Royal Tweed Bridge.
As a result, it was taking drivers half an hour to get from one end of town to the other.
One of those caught up in the tailbacks was John Ferguson, who said: “I think someone should be held to account over this.
“To have the A1 diverted through the town is bad enough but for there then to be roadworks at the Tweedmouth end of the bridge is ridiculous.
“There’s been some really poor planning. It’s another example of how Northumberland County Council behaves towards Berwick.”
The authority revealed that approval for the Tweedmouth work was given by mistake.
A council spokesperson said: “The council would like to apologise for the traffic congestion caused in Berwick last weekend and in particular on Sunday 20th September, as a result of roadworks.
“Co-ordination of work on the highway is a vitally important part of our network management duty and we deal with over 15,000 requests from statutory undertakers, the highways team and event organisers each year.
“Work on the A1 required a diversion through Berwick. Unfortunately not all of the diversionary route information was captured onto our electronic systems, therefore approval for other unrelated works was given in error.
“This was an isolated incident which we regret and apologise for any inconvenience experienced by road users.”
