Answer for Garden Bridge and Rotherhithe/Canary Wharf Bridge Benefit Cost Ratios

Answered By: 
The Mayor

The business case for the Garden Bridge was submitted to and approved by the Department for Transport. The benefit to cost ratio (BCR) of the Garden Bridge is 5.8 to 1.   

TfL recently announced that it would provide funding for the detailed feasibility study for the Sustrans bridge. The BCR is therefore not yet available.
