Excavated material from the Crossrail tunnels can now be delivered by ship to Wallasea Island in the Thames estuary following completion of a new jetty and conveyor system.
The 180m long jetty, constructed by Bam Nuttall, will receive around 4.5M.t of material excavated during Crossrail’s tunnelling operations in London. It will be used to create a new 600ha RSPB nature reserve on the island, 13km north of Southend-on-Sea.
The jetty consists of two 800t steel pontoons, each 15m wide, and can accommodate two 90m, 2,500t ships simultaneously. The first of over 2,000 ship loads will arrive at Wallasea Island later this summer.
Tunnelling for Crossrail will produce in the region of 6M.t of excavated material. The project aims to re-use 100% of the excavated material.
