|Route outline (key)|
In 1935, following the completion of the northern section of the Exeter Bypass, the B3181 took over most of the A378 (the southern end became A38) to its northern terminus at Pinhoe on the A38. This required short multiplexes along the A35 and A30.
In 1977, following the completion of the M5 and general downgrading and renumbering in the Exeter area, it was downgraded, and the number reused for the former A38 elsewhere. The original section of the road remains semi-rural but the 1935 extension now runs through an industrial estate and urban area.
