→South towards Calamarca / Ayo Ayo / Patacamaya / Sica Sica / Caracollo / Cochabamba (via #1 Panamericana and #4 highways)
The first tranca heading south is located in Achica Arriba. Lots of cars and some trucks stop there to eat or for repairs, and of course everyone has to slow down. There is also a gas station just further down the road (though not a very busy one). To get there one can get a van heading to Patacamaya - fare should be ~Bs. 3 (though haggling may well start much higher). These run down Highway 1, many originating from La Ceja. You may also flag one down at the intersection of Tihuanacu and Highway 1, just in front of the Teleférico station 6 de Marzo (though the rush of traffic and excess of buses to other destinations there makes getting one in La Ceja advisable).
Alternately, also at the intersection of Tihuanacu and Highway 1 is a parking lot where lots of truckers wait for cargo. If you head there and chat them up - and are fine waiting until they have the cargo to leave - you could easily find a ride. Most have their destination on a sign in their windshield or on a post at their open cargo beds.
