Workers are paving photovoltaic (PV) devices on a ring road in Jinan, East China's Shandong province, to build a solar system providing power for charging poles. The 2 km long special section of Jinan's southern ring road will be the first PV highway in the world, and will be put into use by the end of December 2017.

The special section will have three layers. The bottom will be an insulating layer to prevent moisture from getting to the PV devices in the middle layer, and the top will be the protection layer built by transparent concrete.
NOTE: Multiple news sources other than China Daily say that the section of PV highway in Jinan is 1 km long and that a mini-bus traveled at the speed of 100 km (62 miles) per hour over the tested road, with the driver praising the braking distance of the new surface as almost identical to that of a traditional asphalt surface.
