This year has been one of milestones reached on the Queensferry Crossing and they are captured in this new video released by project chiefs.
Still on schedule to open in December 2016, the £1.4 billion bridge has also seen some drama unfold.
First workmen discovered historic explosives buried deep in an area of the work site on the north side of the Forth, which led to the temporary closure of the Forth Road Bridge and Forth Bridge while experts blew up the device in a controlled explosion.
Then the need for the new crossing was never so apparent as the day defects on the 51-year-old Forth Road Bridge caused its complete closure.
By the start of this month more than a quarter of the new bridge deck was in place.
Spectacular deck fans around each tower, formed by the stay cables which support the new deck sections, are now dominating the Forth, like giant steel Christmas trees.
Infrastructure Minister Keith Brown said earlier this month: “Everywhere you look major milestones are being reached and significant progress being made.
“To name a few examples, concreting has been completed on the three towers, the south viaduct is complete with the concrete now being poured to complete the deck, final preparations are being made for the imminent launch of the north viaduct and great strides have been taken on the complex new and upgraded road networks to the south and north of the Forth.”
All of this has been achieved in 2015 despite adverse weather throughout the year.
