Excavations for second Tyne vehicle tunnel reach project milestone

Land based cut and cover excavations for the Tyne Tunnel running through Jarrow and East Howdon have been completed, marking a milestone in its progress

Cut and cover at the Tyne Tunnel site

The trench runs from Jarrow and East Howdon

With the cut and cover trench complete, work can begin on the tunnel’s roof and floor slabs. 80% of the concrete floor slabs have already been poured and 37% of the roof slabs are built.

Managing director of TT2, the project’s concessionaire, Trevor Jackson, said:

“Construction work is going well and we’re delighted with the progress we’re making across the site. The trench for the new tunnel now runs the length of the project. With cut and cover excavations complete we’re one step closer to opening the new tunnel in 2011.”

Completion of the cut and cover excavations represents 96% of the land excavations required for the new tunnel. Work is currently underway on the remaining 4% of land excavations required for the two short sections of sprayed concrete lining tunnel in Jarrow. These sections use a specialised technique to tunnel beneath utilities and reinforce the excavation at the same time using sprayed concrete.

Dredging to excavate the trench for the river section of the new vehicle tunnel is due to start within a matter of weeks. At the beginning of November the cutter suction dredger, Vesalius, is due to arrive on the Tyne ready to commence work on dredging a channel within which the river tunnel elements will be placed.

The tunnel elements have already been constructed upriver at a dry dock in Wallsend, ready for immersion beneath the Tyne next year.

  • Well Done!!

    How about a submersed tunnel under the River Forth !!

    A much better idea than another bridge which will be subject to winds and weather and will be inadequate, with only two lanes in each direction.

    Who is thinking, if at all?

  • The shoring of the excavation seem a bit light to me. Is this accepted as OK now?
