 The route is mainly a two-lane roadway even though it has been recently expanded from San Cristobal to Baní and has been largely replaced by the faster DR-6 route from Santo Domingo to San Cristobal.Due to its locality and heavy traffic DR-2 has been undergoing an expansion project to make it a two-lane expressway and allow better traffic flow.DR-2 has one toll location just outside the boundaries of Greater Santo Domingo before entering the town of Haina.
