Waymo’s robotaxis will begin carrying passengers through parts of Atlanta Tuesday in an expansion of a partnership with Uber’s ride-hailing service that began earlier this year in Austin.

Waymo robotaxis are now available exclusively on the Uber app in Atlanta. It’s the second city after Austin host the companies’ burgeoning partnership.

Waymo robotaxis can now be hailed in Atlanta via Uber. The two companies, which already offer the “Waymo on Uber” service in Austin, said on Tuesday the commercial service will initially cover about 65 square miles in Atlanta.
