General description

The New Tyne Crossing in Newcastle, opened to the public in early 2011, doubled the capacity of an existing road structure inaugurated in 1967, thus enabling decongestion of a key route for north-south traffic between Scotland and England. The project, spanning 2.5 kilometres, highlights the breadth of expertise of Bouygues Travaux Publics: an immersed tube tunnel made up of four pre-stressed concrete caissons, earthworks, road works and traditional tunnels, including two tunnels bored using SCL (Sprayed Concrete Lining). Without interruption to the Tyne river traffic, the existing cast-iron segment tunnel was also upgraded to current standards, particularly in terms of lighting, signage, drainage and ventilation. Both the old and new road structures now benefit from, amongst other things, a water mist system for active fire protection, a first in the UK at the time.
