TEC Tunnel Engineering consultants

Project description

For many years serious congestion occurred at peak times on the A19 trunk road at its crossing under the river Tyne east of Newcastle. The bottleneck occurred in the 2 lane bi-directional Tyne Tunnel which was constructed as a bored tunnel (diameter 10.2 m and consisting of cast-iron segments) in the sixties of last century. In the reference design the existing tunnel will carry the northbound traffic (2 lanes), whereas the new tunnel carries the southbound traffic (2 lanes).
