The edge Szeged index of graphs is new topological indices presented very recently, having applications in chemistry. In this paper, a formula for the edge Szeged index of bridge graphs is obtained and some other composite graphs are considered. Applying these formulas, the edge Szeged index of several graphs is computed.
