Work to prepare Wallasea Island in Essex to receive waste from Crossraill construction is continuing, with the construction of a new jetty now in progress.
The island will be used to dispose of 4.5M.t of waste from the project, which will be transported to the site by rail and boat, and used to create a new 607ha nature reserve for the Royal Society for the Protection of Birds. Crossrail has said that this work will create one of the largest new wetland reserves in Europe for 50 years.
Contractor Bam Nuttall is currently working to build the new jetty at Wallasea, which will be capable of handling two 2,500t ships at any one time. The jetty is expected to be completed by next summer.
Excavation of the twin bore 21km tunnels is expected to produce 6M.t of waste, which the organisation has said it expects to be clean. The remaining 1.5M.t will be “used beneficially elsewhere”.
“Crossrail is committed to delivering the new railway in the most sustainable way possible,” said Crossrail programme director Andy Mitchell. “All of the excavated material from Crossrail’s western tunnels will be transported to Wallasea Island by freight train and ship to minimise the number of Crossrail lorries in central London.”
