Overall, the viaduct contained 14,150 cubic meters of masonry, which weighed 34,040 tonnes. It was constructed at a reported cost of roughly £30,000, of which the centring alone cost around £4,500. The viaduct was completed during 1850. It has been claimed that Miller came to regard the Woodroad Viaduct as having been his greatest professional accomplishment. During 2010, the local Woodroad Regeneration Forum and national railway infrastructure company Network Rail embarked upon a joint effort aimed at safeguarding the Woodroad Viaduct and ensuring its long term future. In line with this effort, future work to both restore and upgrade the structure has been planned. On 25 September 2010, Cathy Jamieson, MP and MSP, unveiled a commemorative plaque to mark the passing of 160 years since the construction of the viaduct.
