Changes

Option #1: to get directly to the toll (''péage'') starting the highway A62. From the metro station "La Vache" (Metro line 2), take the bus 29/60/69/105, get off at "Lapin", walk ahead (on Avenue de Front) for about 75 meters and take the first left (Chemin du Lapin) until you reach a pedestrian bridge. From there you can jump across a small barrier, get in something that looks like a small abandoned field and walk along ahead for about 100 meters. You'll see a one-way northbound motorway connection road to what will become the péage after about 500 meters. You want to walk along that portion, staying as much as possible on the right side of the safety barrier (not very dangerous actually, but if the police see you, they won't stop to annoy you). In my opinion (Hertinek, aka Uncle_Franek), this is the ultimate option to hitch north out of Toulouse. I've lived in the area almost all my life, and have experienced many different spots. Today I always use this one. Two busstops after "Lapin" you can leave the bus at stop "Lapparou" as well, walk ahead 50 meters, turn left Impasse des Horticulteurs at the end of which you will find a red wall and fence which you need to climb over, which is probably possible as the fence is damaged - this way you are only a few meters from the péage, which then saves you from walking along the motorway for half a kilometer.
