On Wednesday afternoon, CEO Elon Musk posted a picture of two semis setting out on their first delivery run from the Gigafactory near Reno to the company’s plant in Fremont.

Musk unveiled the big-rig at an event last November, claiming the semi-truck would be capable of traveling 500 miles on an electric charge. The distance between the Gigafactory and the Fremont plant is about 260 miles.

Walmart and Anheuser-Busch are among several major companies who have already placed deposits for the truck, which is expected to cost between $150,000 and $200,000.
