China will build an "intelligent" super expressway, enabling increased safety and higher average traffic speeds, in east China's Zhejiang province by 2022, authorities said on 23 January.
The six-lane, 161-km freeway linking Hangzhou with Ningbo is expected to increase the average traffic speed by 20 to 30 percent, slashing the travel time between the two cities from two hours to just one, Xinhua news agency reported.
China's expressways have speed limits of between 100 and 120 km per hour, with the average traffic speed estimated at 90 kph.
The new intelligent expressway system will incorporate a monitoring system as well as a warning system to maintain the safety of vehicles while increasing the average traffic speed.
China's first solar expressway opened for testing at the end of 2017.
