It is an impressive and highly visible curved sandstone structure. The bridge has historical significance, largely due to its contribution to the early and continuing development of railway infrastructure and services in western NSW in the late nineteenth century and early twentieth century, and also as an example of the use of local sandstone during a period of economic restraint but rapid expansion of railway services during which Whitton was required to use local materials as far as possible in bridge construction. It is a fine, intact and representative example of a stone arch railway viaduct.
