Scheme 1: Take the township road from Pu 'an to Cangxi, the distance is about 90 kilometers, and then drive from Cangxi to Suining, about 160 kilometers, and the whole journey is about 250 kilometers. This section of highway is mainly township kilometers long, with large slope and poor road conditions. As shown below: Pu 'an to Cangxi (90km)
Cangxi to Suining (160km)
Option 2: Go to Suining via Mianyang. The whole journey is about 270 kilometers. Highlight: The overall road conditions are better than those in Scheme 1, especially Miansui Expressway, which has fewer vehicles, good road conditions and an advantage in driving time, saving time than Cangxi. But the toll is higher than scheme one! circuit diagram
