The 1.35 billion-pound ($1.7 billion) Queensferry Crossing, the longest bridge of its type in the world at 1.7 miles (2.7 km), connects the capital Edinburgh to Scotland’s north.
The Queen described all three “magnificent structures” crossing the River Forth, built in three separate centuries, as “feats of modern engineering”.
“The Queensferry crossing joins its iconic and historic neighbors to create not only a breathtaking sight across the Firth of Forth, but to provide an important link for so many in this community and the surrounding areas,” she said in a statement.
Built with 35,000 tonnes of steel and 150,000 tonnes of concrete, the crossing reaches 210 meters (690 ft) above high tide, standing as tall as about 48 London buses stacked on top of each other. Barriers deflect the wind and shield vehicles from the huge gusts common on the Forth.
