Milltown of Rothiemay Bridge spans the River Deveron immediately to the south of the village of the same name. It has never carried a classified road, but it's scale and construction imply that this was an important route in the past. The bridge consists of five spans, four of which are cast iron, while the southernmost span is built from stone. The ironwork is dated 1872, although some records suggest that the bridge wasn't completed until 1874. The bridge piers are all built of stone, and the southern three all stand in the river, with the northern one in what is now a private garden on the riverbank. The lower courses of the piers are built of ashlar, and protected with triangular cutwaters, with a substantial string course above. This acts at the arch spring for all of the arches, and rubble work continues above to the tops of the parapets, with a second string course at road level.
The iron arched spans each consist of 4 fairly simple arched members with open spandrels. These support the roadway above and are topped by typical Victorian iron railings between the stone piers. The stone arch is actually built of Engineers Bricks, with stone spandrels and parapet above. It is not clear why this particular arch was built this way, it certainly does not appear to pre- or post-date the rest of the bridge, so perhaps ground stability required a lighter structure spanning the river, or a more substantial buttress on the south bank. The bridge carries a wide S2 carriageway between pavements, with a capacity far greater than modern traffic levels require!
