The new Queensferry Crossing in numbers

The need for a new bridge emerged in 2004 when inspections of the Forth road bridge’s main cables found a loss of strength.

The Queensferry Crossing will open to traffic this week, more than a decade after plans were first drawn up.

Joining the Forth road and rail bridges connecting Edinburgh and Fife, the long-awaited opening comes among a host of events to mark the occasion, including a public walk across the bridge and a visit from the Queen.

Here we take a look at the Queensferry Crossing in numbers:

:: 1.7 miles across – making it the longest three-tower, cable-stayed bridge in the world.

:: 24 million vehicles are expected to use the crossing each year, easing the strain on the Forth road bridge.

:: £1.45 billion cost of the project, down from the original estimate of £3.2 to £4.2 billion.

:: 35,000 tonnes of steel used during construction, 7,000 tonnes alone for the north and south viaducts.

:: 23,000 miles of cables supporting the bridge, almost enough to wrap around the world.

:: 150,000 tonnes of concrete poured over the course of the project, nearly the same amount used for the entire London Olympic Park and athletes village.

:: 210m tall, making it the tallest structure in Scotland and the highest bridge towers in the UK.

:: 10 million man hours involved in the construction.

:: 122 sections make up the bridge deck, each one weighing up to 750 tonnes.

:: 65 options were considered before the cable-stayed bridge design of the Queensferry Crossing was selected.
