A consortium made up of Cintra, Aberdeen Standard Investments and Macquarie Capital will build the new Silvertown Tunnel under the River Thames in the UK. The new tunnel is expected to cost £1 billion to construct. The tunnel will link the Greenwich Peninsula on the southern side of the Thames with Silvertown on the northern side. Construction of this new link will help reduce congestion on the existing Blackwall Tunnel, which is notorious for lengthy traffic delays at present. When the tunnel opens, it will lie within the new ultra-low emission zone (ULEZ) which is being expanded in 2021. The new tunnel was originally anticipated to be ready for use in 2023 but is now expected to open to traffic in early 2025.
