The San Salvador Metropolitan Area Integrated System of Transportation (SITRAMSS) is a proposed high-volume bus transportation system. The first route of the SITRAMSS will make a round trip from San Martin, through Ilopango, Soyapango, San Salvador, and Antiguo Cuscatlan to Santa Tecla. It is projected that between 40 and 60 busses capable of carrying 160 passengers per trip will start operating in the second half of 2013.
