Hitchhiking out
North towards Tucuman, Salta
Take bus 112 from Rivadavia street one block from the terminal, it cost 10 pesos (May 2018) and you need the transport card but you can ask to someone inside to pay for your trip and give them cash back. Get down before the ring road (la Rotonda) where the RN9 starts and walk along north for 300 meters to the police control point, you can hitch right after them.
