Drivers have been urged not to rely on their satnavs when they use the new Queensferry Crossing - because the devices don’t think it exists.
Bemused motorists have branded it “astonishing” that the GPS company has not updated its maps.
Instead TomTom satnavs are advising drivers to do a U-turn on the bridge - or take a detour via Falkirk.
One driver said: “I headed over and it looked like I was crossing the Forth on a boat. It is astonishing that companies can’t update their systems almost immediately.”
It comes as the bridge has been plagued with tailbacks. Infrastructure Secretary Keith Brown said: “Hopefully, when it becomes less of a novelty, it will improve further,” he said.
