Two workers were spotted dangling as they treated the Queensferry Crossing with what is believed to be de-icer as we move into the colder winter months.
Onlookers stopped in shock and awe in order to take in the views and to capture a picture of the two men at work.
The pair can be seen hanging from the 210 metre structure - which is 50 metres taller than the older Forth Road Bridge.

Michael Hance, who was walking on the Forth Road bridge said that he spotted something in the distance when he looked across to the Queensferry Crossing.
He said: “At first we thought it was something that had got caught on the cables, then we saw them moving. Then you realised that it was legs dangling.
“I think it’s something to do with the de-icing process as one of the men working on the Crossing commented on my photo to say as much.
“No one was panicking but you did get people stopping and taking pictures. We spotted the men from the old Forth Road bridge, where I captured them on my phone.”
One of the workers appeared to comment on a post on Facebook, stating: “Yes that is me and my work colleague today on the Queensferry Crossing.
“It’s pure graft mate.”
The Queensferry Crossing spans 1.7 miles making it the longest three-tower, cable-stayed bridge in the world.
It’s construction had set a world record in 2013 when it achieved the largest continuous underwater concrete pour. The 24-hour non-stop operation successfully poured 16,869 cubic metres of concrete into the water-filled south tower caisson.
Prior to the completion of the final closure sections on the deck, the balanced cantilevers which extend 322m north and south from the central tower, i.e. 644m tip to tip, were recorded by Guinness as the longest ever.
They are also the highest bridge towers in the UK at 210m tall.
