The letter prefix G, which stands for Guodao (Chinese: 国道), literally meaning national road, is used for national expressways, and the letter prefix S, which stands for Shengdao (Chinese: 省道), literally meaning provincial road, is used for provincial expressways.

In addition, there are 14 national-level expressways that are entirely in or will pass through the province.
