I had a firkle round the 1911 census and the 1910 Ward's Directory of Newcastle.
One address in the 1911 was given as 5 Dickinson Crescent OR 72 Salter's Road.
The Wards directory had Dickinson Crescent listed but says (see Salter's Road)
Both of these suggest that Dickinson Crescent was probably a block of houses within Salter's Road and would be known by both names. Its fairly common for long roads to be subdivided into Terraces or Crescents.
What surname are you looking for? (PM me if you don't want to post it in here) and I can check the Directory.
Or if you have access to Ancestry (or can get to a library) look at the Wards Directory, if your Granda was there in 1910 he may be listed. which may give you the house number applicable to Salter's Road - if that makes sense. The building 'may' still exist.
