Transport authorities in Jiangsu have announced a plan to rename all its national and provincial expressways as part of a nationwide effort to standardise the names of all expressways. Work will start in November and is due to finish by June next year. All national expressways will start with G (as in Guodao) and provincial expressways will start with S (as in Shengdao).

According to the provincial plan, by 2015 Jiangsu will have 46 expressways totalling 5,200km. Fourteen of them will be national expressways totalling 2,900km, and the remaining 32 will be provincial ones totalling 2,300km.
