The present bridge replaces a two-arched bridge of 32 feet (9.8 m) span built by George Wade as part of a military road.

[1][2] The old bridge was washed away in the floods of 1829, and the present one put up some time after.

[3] It has a single arch of 17.8 metres (58 ft) span, and rises high above the flat ground around it.

[1] It is about 4.3 metres (14 ft) wide, with metal railings instead of parapets.

[1] Despite being more modern than many other stone bridges, Sluggan bridge is of a more old-fashioned construction.
