Find any underground/metro station (Blue line no. 1) and take the metro to the Slivnitsa (Сливница) stop (direction: Obelya - Обеля). When you get out, you will see a big crossroad - follow the direction out of the city. There are roadsigns that say [[Belgrade]] - that is the right direction. You can try to get a lift there but there are still too many local commuters passing. It is much better to take a bus no. 54 and get off when you see Metro hypermarket. There is a petrol station and traffic lights so the traffic is pretty slow.

Take tram 22 in direction east, get off at the last stop. The road parallel to the tramline runs directly out of the city, its possible to hitch anywhere from here but I would suggest a better place after the ring road which isolates only the traffic running to the A2 motorway. 7 km up the road is a Shell petrol station, the last stop for gas before the motorway, you can either walk the 7 km straight up the road or if you look to the left you will see a carpark in front of a car dealership. This is the bus station, take either the 117, 90 or 12, all will run directly up the road and stop more or less in front of the Shell petrol station. You can choose either the petrol station or just up the road is also ideal for hitching. Another option is to take the 90 and persist with it until you reach Gorni Bogrov, where you can hitch-hike from the bus station directly with great success since it has a lot of room for stopping and cars drive slow.
