|Route outline (key)|
The A180 appears in the 1922 Road Lists as Durham Coast Road (proposed new road).
The road would have started on the then-A19 (now B1432) in Easington and run southeast through what is now Peterlee and Hartlepool (then called West Hartlepool: today's Hartlepool consisted of two separate towns in the 1920s) before terminating on the A178 near the mouth of the Tees to the south of Seaton Carew.
The section from Easington to Hartlepool was built in the mid 1920s, and opened as the A1086, which it remains. The Hartlepool bypass section, however, was never built. The idea to number the coast road as the A180 must have been abandoned in the 1920s as the number was allocated to a short link near Durham.
The A180 does not appear on contemporary MOT maps as under construction (unlike, say, the A2 Dartford Bypass, A4 Great West Road and A36 Portway) and is believed to be the only road in the 1922 list allocated to a proposed, but unbuilt, route, as opposed to a road that was under construction but had not yet opened.
