Gyrnos or Gurnos Tramroad was built by the ironmaster William Crawshay in 1792 to carry limestone from Gyrnos Quarry to Cyfarthfa Ironworks (nprn 34078). The tramroad ran south from the quarry, serving a bank of three limekilns at SO 0379 0749, and continuing over Pont-y-cafnau (nprn 34860) to the ironworks, a total distance of approximately 1.8km.
