Derby Highway Wikipedia
Derby Highway is the western terminus of the popular Gibb River Road. It is also a useful access for many local fishing "secret spots" at the mouth of the Fitzroy River, with one of the better known ones being the Cuttings.
A staged reconstruction of the highway has been taking place in recent years. So far, approximately 15 kilometres (9.3 mi) of the highway has been reconstructed and widened, with plans for the remainder to be completed in the near future.
