 Take a the bus number 6 from ''Place de la République'' 111 direction '''''La Maxe''''' from for example Boulevard Poincaré (right by the river, about a 10-minute walk from Place de République) and go to the last stop (the ticket is 1,20 50 EUR). From there walk west, walk over the motorway and walk further on the same street around 2 km until you see the a petrol station. When you see the petrol station, it is better to walk about 500 metres further and walk into the station along the motorway (there's a little path that will bring you on the motorway). From the this petrol station, it is easy to get rides directly to Lyon or even further.
