Circa 1873. Skewed cast-iron arch bridge, open spandrel, with 4 ribs and solid cast-iron plate parapets with broad panels separated by narrow strips with rounded heads. Faces of external arch ribs decorated with moulded strips to emphasise arch form. Massive stone abutments, wing walls and associated parapets of bull-faced ashlar, with polished string course at road level and polished copes. Terminal pilasters and dies.

Statement of Special Interest

A good unaltered example of a cast-iron arch railway overbridge. A similar bridge of the same date on the Lanark branch still carries the main road traffic, but has had its parapets reduced. The bridge carried what was the main access roadway from the Hyndford Road (A73) into the Bonnington Estate, passing Bonnington Mains Farm en route to Bonnington House. It also carried traffic to Robbiesland Farm which was also originally part of the estate. Maps indicate that there were several tracks in to the estate, the tourist route being that from the S end of New Lanark and on which there was a gatekeeper who issued tickets.

The earliest part of this railway was constructed by the Lanark Railway Line but it was taken over by the Caledonian Railway in 1855. The Lanark to Douglas branch opened on 1 April 1864 and the extension to Muirkirk over which this bridge spanned was opened for goods on 1 January 1873 and for passengers on 1 June 1874.

About Listed Buildings

Listing is the way that a building or structure of special architectural or historic interest is recognised by law through the Planning (Listed Buildings and Conservation Areas) (Scotland) Act 1997.

We list buildings of special architectural or historic interest using the criteria published in the Historic Environment Scotland Policy Statement.

The information in the listed building record gives an indication of the special architectural or historic interest of the listed building(s). It is not a definitive historical account or a complete description of the building(s). The format of the listed building record has changed over time. Earlier records may be brief and some information will not have been recorded.

The only legal part of the listing is the address/name of site. Addresses and building names may have changed since the date of listing and if a number or name is missing from a listing address it may still be listed. Listing covers both the exterior and the interior and any object or structure fixed to the building. Listing can also cover structures not physically attached but which are part of the curtilage of the building, such as boundary walls, gates, gatepiers, ancillary buildings etc. The planning authority is responsible for advising on what is covered by the listing including the curtilage of a listed building. Since 1 October 2015 we have been able to exclude items from a listing. If part of a building is not listed, it will say that it is excluded in the statutory address and in the statement of special interest in the listed building record. The statement will use the word 'excluding' and quote the relevant section of the Historic Environment Scotland Act 2014. Some earlier listed building records may use the word 'excluding', but if the Act is not quoted, the record has not been revised to reflect current legislation.

If you want to alter, extend or demolish a listed building you need to contact your planning authority to see if you need listed building consent. The planning authority advises on the need for listed building consent and they also decide what a listing covers. The planning authority is the main point of contact for all applications for listed building consent.
