The cut and cover construction would involve maximum excavations of approximately 20 metres deep in North Tyneside and 30 metres deep in South Tyneside. 

The ground is cleared before construction commences. Diaphragm walls or piles are sunk into the ground from the surface. These retain the soil when excavation commences.	Excavation between the walls commences. As the trench becomes deeper, props are installed to support the structure, and prevent ground movement.
At the bottom of the excavation, the construction of the tunnel can commence.	The tunnel construction is completed and the trench is backfilled with material previously excavated.The area is now ready for restoration.
