the idea is sound. you arrive on a bus from, say, puerto plata. instead of ploughing through the traffic to get to the city centre you get out at the bus station and take teleferico/metro to the city. pretty neat.
and it's an interesting approach to the destruction of the transport mafia. all the do is offer a choice. passive attitude. smart.
as far as connecting with the east: there may be more to come. already if someone arrives in metro or caribe they have to transfer to another location to go to punta cana, correct? and isn't there a plan for circunvalacion of SD to run through los alcarrizos? since i do not live in SD i do not know how advanced the works are.
