McMillans Bridge was originally constructed in 1856 with stone abutments and timber truss, by the Victorian Central Road Board to a design of Charles Rowland, a student of prominent colonial engineer David Lennox.[2] In 1888-9 the timber span was replaced with a riveted wrought iron truss designed be Charles Anthony Corbett Wilson by for the Shires of Leigh and Grenville. Wilson was a particularly prolific Victorian shire engineer who was influenced in this and Pitfield Bridge by the lightweight and efficient metal truss designs of Professor W. C. Kernot of Melbourne University.[3]

The 1889 wrought-iron spans were fabricated in Geelong at the Humble and Nicholson Vulcan Foundry and comprise two double-intersection deck-trusses, connected by iron cross bracing, and seated on the 1856 abutments of red sandstone. These abutments were originally made for a timber truss superstructure, which lasted only 33 years. The timber deck has a single layer of longitudinal planking on timber cross beams, which are bolted to the flanges of the truss top chords. The single span is 29 metres long with a deck 6.1 metres wide, later widened to 7.3 metres. The wrought-iron lattice-girder trusses are of unusually light construction.[2]

The Bridge is listed on the Victorian Heritage Register.[2]
