Evaluation

A single-span road bridge, dated 1859, carrying Knock Road over Douglas Burn. The bridge, built during the mid-nineteenth century, remains unchanged and retains ashlar stonework punctuated by string course and rubble parapet. Although an interesting example of industrial archaeology the bridge is not of sufficient interest to warrant listing.
