Draw Village and Super-Road, play both, and you end up with an 8-card hand and one Action, just like if you played three Labs. Get another Village through that and play it and you end up with an 11-card hand.
Unlike other Actions, most relevantly Smithy, Road doesn't leave your hand when you play it. It does, however, ensure that whenever you're done playing Roads, you'll still have one left in your hand and likely dead, decreasing the total card gain by 1. But there are still ways of making use of that, such as cards with discarding or top-deck effects.
