The proposed bus would span two traffic lanes and carry up to 1,400 passengers in articulated segments, at speeds up to 60 kilometres per hour.
It would run on special tracks built on either side of the lanes, with 2.1 metres of clearance underneath.
Animations of the bus show the underside simulating the sky, to make it look less like a tunnel, while windows in the sides let drivers see out.
Passengers would board and disembark via ramps that unfold and extend from the sides, and it would have boom gates to stop traffic if necessary.
The Beijing-based company Transit Explore Bus is currently building a life-size model in Changzhou and they plan to test it in July or August, according to the Xinhua news agency.
Chief engineer Song Youzhou told Xinhua that each elevated bus would take the place of 40 conventional buses and, because it is designed to run on electricity, could cut annual fuel consumption by 800 tons and carbon emissions by almost 2,500 tons.
