The change of typical crack, especially the change of typical crack width, can intuitively reflect the technical condition of the bridge. Based on the long-term monitoring of the typical crack width of two highway bridges, the article introduces the current main monitoring methods of bridge crack width, their applicable conditions and their advantages and disadvantages. Meanwhile, by analyzing and studying on some of the burgeoning monitoring methods, the article gets the current best and suitable method for the monitoring of bridge crack width. Engineering example proves that the method is simple,effective and practical.
