Cataractonium was a crossroads where the road north from Eboracum (York) and Isurium (Aldborough) split into Dere Street running 12 Roman miles northeast to Vinovium (Binchester) and the Roman equivalent of Watling Street running 16 or 18 Roman miles northwest to Lavatrae (Bowes). These roads communicated with and supplied Hadrian's and the Antonine Wall.
