Great Eastern Street

Great Eastern Street was a street in Shoreditch.

Following their return to London on 26 June 1965, Barbara Wright and Ian Chesterton took a bus to Old Street, before walking down Great Eastern Street for 10 minutes. At the intersection between Great Eastern Street and Hollywell Lane, they headed towards Joan Wright's house on Arnold Circus via Redchurch Street. (PROSE: The Time Travellers)

The street was not far from the house of Charlie Smith and Miss Quill. John O'Donnell was running along Great Eastern Street in Ram Singh's body when their body swap was reversed. (PROSE: Joyride)

Behind the scenes
Although not stated in the novel explicitly, it can be inferred that Great Eastern Street is in Shoreditch because O'Donnell goes from 1 Wellington Road, which is in Shoreditch to Swallow Avenue, which is also in Shoreditch, via Great Eastern Street.
