|Route outline (key)|
The A108 number was used for the Sunderland bypass and the route north through the Tyne Tunnel from the tunnel opening in 1967, although the bridge over the River Wear did not open until 1975 meaning through traffic still needed to go through Sunderland.
When the A1 was re-routed via the Tyne Tunnel in 1978 to bypass central Newcastle upon Tyne it took over the northern section of A108, from West Boldon to Seaton Burn. The remainder of the road became A19, with the old A19 to South Shields being renumbered to A1018.
Today the entire route is numbered A19.
