VolkerStevin Marine this week floated the first of the four 90m long caissons that will form the bulk of the new Tyne Tunnel.
It was moved from their dry dock location in Newcastle down the River Tyne to its final destination.
Now berthed in Howdon Basin 3km down river, this first tunnel section is set to be sunk into position on the river bed in the next few days.
The remaining three sections of the tunnel will be floated down river over the next six weeks and will be lowered sequentially in to place.
Each reinforced concrete element is 90m long, 15m wide and 8.5m deep and weighs 10,000t.
VolkerStevin Marine is main contractor for the £16M contract to manufacture, transport and immerse the New Tyne Crossing’s tunnel elements for client Bouygues Travaux Publics.
