Roads North of the Thames

In the coming weeks we will also begin our search for partners for the Roads North contract – to build the new routes north of the river.

Tunnels and systems

At 16 metres wide, our tunnels will be some of the largest bored tunnels in the world.  They will also be the longest road tunnels in the UK. We have invited tenders to build the road tunnel that sits at the heart of the proposed Crossing, the most ambitious roads project for a generation.

Kent Roads

In the coming weeks we will also begin our search for partners for the Kent Roads contract – to build the new routes south of the river.
