Definition
开通 (kāi tōng) means to open a new route/line, launch a service, or subscribe to a membership — it's about making something available or accessible. It differs from 推出 (tuī chū), which launches a product, and from 订阅 (dìng yuè), which subscribes to publications. For roads/railways, 通车 (tōng chē) specifically means the line is open to traffic, while 开通 is the act of opening it.
