The maps all show the road this bridge is on as McAdam Road, although it is likely it was once the old River Drive. This bridge was likely closed because nearby Kerwood Road Bridge essentially bypassed the bridge and made it redundant. The bridge was still in use by a local four-wheeler during the field visit, as the bridge is technically closed to traffic, but not blocked by anything other than a post. There is no reason why this bridge could not be restored for light traffic or non-motorized traffic. It has great significance as a historically intact example of an unusual bridge design apparently built off and on around this areas of Ontario presumably by the Hamilton Bridge Company. There is another bridge very similar to this one on Cameron Road in Lambton County. The truss configuration is double-intersection Warren with some additional vertical members. The McAdam Road Bridge varies from the Cameron Road Bridge a bit, mainly in terms of its members and chords design. Where all the members and chords on Cameron Road had lattice, all the members and chords on McAdam Road have v-lacing. The Cameron Road Bridge appears to be a slightly longer structure, so perhaps that is why the larger latticed members were used. This bridge design is noted for a shallow endpost slope angle. This may explain why there are those extra members leading from half-way up the endpost to the bottom chord. Unlike Cameron Road, this bridge retains its original lattice railings.
