|Route outline (key)|
The original B3173 was a short B-road in east Devon.
It started in the centre of Seaton, where it terminated end-on with the B3172, and headed west through Beer, before turning north west up to Hangman's Stone on the A35. In 1935 the route west of Beer became part of the extended B3174 whilst the section to the east became an extension of the B3172. There was later a slight re-alignment of the main road through Beer to ease the ascent of the hill and the B3174 now heads east to Seaton as the B3173 did.
