CrossrailPlus extension via Metrotidal tunnel 

BENEFITS

Metrotidal integrates three separate engineering agendas; new transport infrastructure, flood defence and tidal power, to create a single project with high net economic benefits and significantly reduced costs. The new connections and power generation provide a network for green-growth to the east of London.

Core benefits:

• new rail and roads orbitals for the Thames Gateway
• new north-south arteries for the Greater Southeast
• enabling and spreading green growth uniformly across the Thames Gateway Region
• carbon-neutral operation of tunnel and new rail services
• extension of Crossrail to form an orbital “Crossrail Plus”
• a rail-freight bypass East of London
• relief of congestion on the M25/ Dartford Crossing
• a rail-freight connection for East coast ports to the Chunnel
• Midlands/Stansted/Ebbsfleet/Paris rail service
• air-rail substitution via HS1 and Stansted
• next generation of flood defences for London
• tidal power generation for green growth in the Thames Gateway
• removal of pylons
• dry dock facility
• a South West Canvey Regeneration Zone
• minimal land take with short and narrow new transport corridors
