Route

Gansu

The expressway is complete from Lanzhou to Weiyuan County in Dingxi, and under construction until Longnan. From Lanzhou the expressway enters the New Qidaoliang tunnel through the Xinglongshan mountains, from where it follows the Tao River parallel to G212. Past Lintao, the route diverges from the Tao river valley and passes through hilly landscape through a couple of tunnels until exiting in the Wei River valley. From there it continues Provincial Expressway 14, and the under construction section of G75 exits. In Min County, the expressway will be parallel to G212 again until Longnan, exiting Gansu through a mountainous valley by numerous tunnels and viaducts.
The terminus of G75 has been the site of hundreds of accidents, totaling at least 42 deaths since 2012. Over a distance of, the road descends. Trucks having brake failure or being overloaded, and drunk drivers cause most of the accidents. The toll station is located several kilometers from the actual terminus of the expressway to reduce the severity of accidents.
