China has the world’s largest road network with a total 4.7 million kilometers of road in use and an expressway distance of more than 130,000 kilometers.

As China's economy grows even more, keeping the country (with the largest population in the world) on the move has become a priority for the Chinese government.

Since participating in the construction of Mianyang-Guangdong (绵阳-广州) expressway in 1999, Ranken has been involved in the construction projects of 16 expressways in Huabei (华北) district and Southwest China.

Despite working under difficult soil conditions and challenging engineering issues, Ranken has accumulated the specialised earthwork construction knowledge and tunnelling experience to complete projects safely on a timely and cost-effective basis.
