The Queensferry Crossing has reopened after being closed since Monday evening because of falling ice.
The bridge connecting Edinburgh and Fife was shut after ice falling from the cables damaged eight vehicles.
Amey, the bridge operators, said its engineers were now “confident” that the risk of further snow and ice build-up had passed.
It was the first time the bridge had been closed since it was opened in August 2017.
Mark Arndt, from Amey, said: “We thank drivers for their patience and understanding during this closure.
“Safety had to come first, however the data we have gathered has improved our understanding of the issue and will help us to improve predictions and refine operating procedures in future.”
He said that engineers would continue monitor the bridge as wintry weather continued over the next few days.
