Provincial-level Expressways
Designations for provincial-level and federal-level expressways in Shanghai had the letter prefix A before the number of the expressway. Starting at the Yingbin Expressway, which was designated the number 1, the numbers increased clockwise around the city. For ring expressways, the designations A20, A30, A40, etc., were used. For expressways connecting to other provinces which already had national designations (beginning with the letter G), designations with the letter A were attached.
In August 2009, Shanghai replaced its system of naming expressways with the prefix A with the letter prefix S, in order to conform to the general designations for provincial-level highways. The S means Shengdao, or provincial-level roads. The letter prefix A was abolished.
