|Route outline (key)|
The B3176 is a short road in east Devon that was once much longer.
It currently starts on the seafront in Sidmouth, at the southern end of the B3175 (although the section along the Esplanade was originally unclassified). It soon turns right at a mini-roundabout onto Station Road and climbs up out of town to end on the A3052 (formerly A35) at Bowd.
Originally it continued on the far side of the crossroads via Ottery St Mary, Talaton and Clyst Hydon to end on the A38 at Westcott, near Bradninch.
When the A38 moved to the Cullompton Bypass in 1968, the B3176 took over the entire of the pre-bypass road, continuing south a short distance, nearly to Hele, and north a much longer distance, through Cullompton to the southern edge of Willand. With the upgrading of the Cullompton bypass to M5 in 1975 and the downgrading of all the A38 in this area, that section of the B3176 has been renumbered to B3181; meanwhile, the original B3176 north of Bowd is now unclassified.
