However, Transport for London (TfL) stated that the charges have not yet been finalized and that any timings and amounts listed on the draft signage application are only suggestive in order to receive clearance.
A representative for Transport for London stated: “The final [decisions on] charges will be made ahead of the Silvertown Tunnel opening in 2025, once further modelling, including assessments on concessions, are completed.”

Drivers will be charged for using the Blackwall Tunnel.
