Matthew's objections were not heeded, and were not persisted in once Parliament had passed the Bill authorising construction of the Tay Bridge. During construction of the bridge some of Matthew's criticisms were borne out: it became apparent that bedrock could not be found at a depth allowing the use of brick piers; the design had to be modified to use lattice-work iron piers of reduced width, and there was considerable cost overrun. The bridge opened in June 1878 and was destroyed in a storm in December 1879: the lattice work piers supporting the centre section of the bridge ("the high girders") failed catastrophically as a train was crossing the bridge. The high girders and the train fell into the Tay and about seventy-five lives were lost. Whilst it was recalled in the immediate aftermath of the disaster that Matthew had predicted collapse in a high wind as one of the horrible ends to which a bridge at Dundee could come, the disaster is generally ascribed to defects in the design and manufacture of the lattice work piers introduced into the design well after Matthew's campaign against the bridge.
