The A3049 number was was originally allocated to Western Road, which cut the south west corner between the A3 and the A27 just north of the bridge with Portsea Island, allowing traffic to avoid Cosham.
The road did not exist in 1922 but must have come into being shortly afterwards, as the A3049 number is the first A3xxx number to be allocated after the original 1922 classification.
In 1935 it became a spur of the A27. After the Cosham and Havant bypasses were built, it became the mainline of the A27 in its own right. The road has since been upgraded heavily and would be unrecognisable from its A3049 heyday.
