Kilmarnock Viaduct

Kilmarnock Viaduct is a railway viaduct built in 1848, featuring 23 arches. It is constructed from coursed squared rubble with polished ashlar dressings and a parapet.

On the south and north elevations, the 23 segmental arches rise from piers that have moulded impost courses. The span is wider at Portland Street, where there are raised rusticated flanking piers and polished quoins. The arches to the west of Portland Street decrease in span and have shallow pointed heads. To the east, near the weir, there is a pair of piers on heavy rusticated cutwaters located in the Kilmarnock Water, with the piers immediately flanking inset into the river bank. There is a manmade soil embankment to the east, which runs parallel with Kay Park and London Road. This embankment features an arched coursed sandstone ashlar wall at the base, supported by sloped buttresses and topped with squared copes.
