Please set out in detail how, in just three years, TfL’s estimate of the cost of a proposed Rotherhithe to Canary Wharf pedestrian and cycling bridge escalated from £100 million to potentially over £600 million.

The development of the Rotherhithe to Canary Wharf bridge scheme and associated cost estimates was discussed at a London Assembly Transport Committee meeting in July 2019. The minutes and transcript of that meeting are available online at the link below. This confirms how Transport for London (TfL) developed the scheme through to concept design, the complexities of building what would be one of the largest opening pedestrian and cycle bridges in the world, and the process of producing the cost estimates. It is important to note that TfL at no point estimated the cost of a bridge at £100 million. https://www.london.gov.uk/about-us/londonassembly/meetings/ieListDocuments.aspx?CId=173&MId=6789
