All of those existed before Romans. From Sumeria to Indus Valley civilization to Egypt. If you dive into their history and watch related channels, you will find even more amazing things. What Romans did, however, was building them systematically and in a standardized fashion to bring them everywhere. That is an innovation.

Aside from that and what advances Rome was able to do from their inception until the Late Republic period, Romans did not innovate as you would describe it. That's why the Roman history from Middle Republic until its fall is a story of slow decline and deterioration into feudalism.
