BEIJING, China (KRON) — China did a test run on Wednesday of an elevated bus that straddles roads, according to CNN Money.

The bus actually rides over traffic and on tracks.

The transit elevated bus is about 70 feet long and carries up to 300 passengers.

Up to four of them can be connected.

It runs on electricity and solar power, and each one could replace 40 standard buses.

The goal is to ease traffic congestion and pollution.

Wednesday’s test was on a straight, nearly thousand-foot track to test brake and power usage.KRON’s Lindsay Clark and CNN contributed to this report.
