From the Oxford English Dictionary , it’s the adverb any road :
Chiefly Eng. regional (north. and midl. ).There’s a wonderful Beatles clip in which John Lennon introduces “Help!”: “The next song we’d like to sing is our latest record, or our latest electronic noise, depending on whose side you’re on. Any road, we’d like to carry on with it.”
As sentence adverb: at any rate, in any case = ANYWAY adv. 2a. Also used to end a conversation, change topic, or return to a topic after an interruption; = ANYWAY adv. 2d.
