Beyond Malton, there is a postulated stretch of Roman road leading towards York, which may be an extension of the causeway. Evidence for it is very slim: Drake mentioned it in 1736, but Codrington could find no trace of it in 1903, and writes that there is "some uncertainty as to the connexion". Archaeologists Philip Corder and John Kirk reported a possible section of Roman road at Brandrith Farm () in 1928, but it is unknown whether this relates to the same structure as Drake observed, or has any association with the Wheeldale structure.
