Re my question 2024/0521: TfL has claimed that an unexpected northbound blockage of the Blackwall Tunnel for six minutes will lead to a 3 mile tailback (https://content.tfl.gov.uk/silvertown-consultation-booklet.pdf). You state in your answer that the entrance to Blackwall is a quarter of a mile from the entrance to Silvertown. Do you agree that, given this, when Blackwall northbound is unexpectedly blocked, it will in fact take about 30 seconds for the resulting tailback to extend past the Silvertown exit?
