B roads in Zone 3 of the Great Britain numbering scheme


B roads are numbered routes in Great Britain of lesser importance than A roads. See the article Great Britain road numbering scheme for the rationale behind the numbers allocated.

There was another B3165: from the B3166, along Stratford Road, Ash Vale.

Indication of a loop back through Penhallick to the B3293 at Zoar appears to be erroneous.
