Rotherhithe to Canary Wharf bridge

Answered By: 
The Mayor

Following the Transport Committee session on 19 July, attended by Heidi Alexander, my Deputy Mayor for Transport, Transport for London (TfL) provided to the Committee a breakdown of the costs for the bridge, which are set out below. The session on 19 July also included a detailed discussion on how the costs were produced and the process of engagement TfL conducted with industry to verify the estimates were robust.  It would not be appropriate to share an item-by-item breakdown of expenditure, as although the bridge option has been paused, it may be something that is reconsidered in future. If the circumstances were to change, TfL would want to ensure best value for the public sector.
