The Queensferry Crossing is due to open in May 2017. The stunning, globally unique bridge forms the centrepiece of a major upgrade to the important cross-Forth transport corridor in the east of Scotland, representing a total Scottish Government investment of £1.35bn (at 2016 prices). The 1.7 miles (2.7km) structure will be the longest three-tower, cable-stayed bridge in the world and also by far the largest to feature cables which cross mid-span. This innovative design provides extra strength and stiffness, allowing the towers and the deck to be more slender and elegant.
