Chengdu-Yibin Expressway in Sichuan province

The Chengdu-Yibin Expressway opened to traffic in the end of 2020. With a total investment of 24.6 billion yuan ($3.75 billion), the two-direction six-lane road is constructed following the highest design standard in Sichuan province. The 157 km long road has reduced travel from Chengdu's Tianfu International Airport to Yibin to 90 minutes.

The road will be digitalized in the next three to five years. "Auto pilot" infrastructures will first be mounted in a 10 km long section, making it comply with the level 3.5 auto pilot standard. Next, a car-to-road coordination system will be established along the road, realizing functions such as video analysis, traffic forecast and alerting. The 5G signal coverage of the road will be completed by June 2021.
