Currently, the expressway is complete in its entirety in Heilongjiang Province, from Suifenhe to just northwest of Qiqihar.

The section in Inner Mongolia, from Arun Banner to Manzhouli, is in the planning stage and not yet built.

[1] Both ends of the expressway terminate at border towns with Russia.

Suifenhe is the location of a border crossing with Russian locality of Pogranichny in Primorsky Krai.

The expressway parallels much of China National Highway 301, a highway that connects Suifenhe and Manzhouli, and the Chinese Eastern Railway between the two cities.
