Acting as a forensic investigator, can you solve the riddle of why the Tay Bridge collapsed?

Each section contains direct contemporary evidence for you to consider: eye witness reports, photographs, metal testing reports, engineer statements.

When looking at the evidence, you should assess how reliable it might be and whether it contradicts another piece of evidence. You can also read related extracts from the Chairman’s report from the Board of Trade inquiry. Although this is the official report, it is the Chairman’s conclusions, which you may not necessarily agree with.

This interactive tool will generate a response based on your analysis of the evidence and point towards a conclusion for the Tay Bridge disaster.
