Template:Infobox Erfurt is the capital of the German federal state Thuringia.
Find out more about public transportation (bus/tram) at the EVAG website.
Option 1: Take the tram number 4 in the direction 'Flughafen Erfurt' (Erfurt airport). Exit at "Volkenroder Weg" and you'll see two petrol stations. Between them there is enough space for cars to stop if you stand on the roadside with a sign "A71".
Option 2: Take the Bus 155 to Kranichfeld (or Lichtenberg) and get off at Haarberg. The bus station is about 1km away from the ramp and next to a parking lot. Better bring a sign that points out your direction.
Option 3: On B7, shortly before the interchange with A71 (Eisenacher Straße corner to Hersfelder Straße), there is a large IKEA you reach it by bus 80 (Friendstedt), 891 (Gotha Hauptbahnhof) or 894 (Bienstädt)) furniture market where it should be possible to find more than a handful of drivers that can bring you to any place in the region or the Autobahn A71
Option 4: During rush hour (from 3pm to 5pm) a lot of cars are leaving Erfurt in direction Weimar or Jena. Go to Weimarsche Straße. There are two lanes and traffic lights and a bike path along the road. It does not have a border stone so cars can stop easily. Bring a sign "JENA" or "A4". People might take you along the Bundesstraße or to the gas station "Eichelborn" which is only several kilometers after entering the A4 eastwards.
Only south towards Würzburg (Autobahn A71)
If you don't mind to take a train, take the regional one towards Ilmenau. Get off in Geraberg (40 minutes ride, ~5€, only once per hour) and follow "Bahnhofsstraße" in direction city center to it's end. Turn right on "Arnstädter Straße" and then the second left on "Talstraße". After passing the last house to your right, turn right and walk the field path approximatly ten minutes to the gas stations "Thüringer Wald Nord". On your way you'll cross beneath the Autobahn.
West towards Gotha or Eisenach (Bundestraße B7)
Take tram number 2 from the city center to the commercial fairground and exhibition center Messe Erfurt to the stop 'mdr/kinderkanal' or 'messe', walk over 'Gothaer Straße' to the 'Real' supermarket and ask drivers standing at the traffic light.
As most people tend to pass Erfurt on Autobahn A4 ask to be dropped of at "Urbicher Kreuz". It's a five minutes ride from the exit "Erfurt-Ost". There you can catch the tram number 3 which takes you to the city center.
