 In 1851 the railway's owners announced that they planned to divert the river down the new cut, but the plan was never realised and a three span bridge was built replacing the wooden bridge.By 1854 there were three separate mills and "The Millers Arms Inn" in the close area.The new cut was unconnected to the Calder River, the part north of the five span bridge was partially filled andused for the construction of a dyework (later becoming "Calder Vale Mill"), the southern part was used as a mill pond.
