Coming from Düsseldorf or Dortmund on the A 46:

Take the autobahn exit Wuppertal-Elberfeld (exit 34).* Turn right if coming from the direction of Düsseldorf, turn left if coming from the direction of Dortmund (across the bridge). Keep left immediately after the exit, then at the first set of traffic lights turn left and stay in the left-hand lane. Straight after the traffic lights turn left again onto Schwesterstraße and follow the road for approximately 300 m until the first right-hand bend. You will see the entrance to Thielenhaus Technologies on the left-hand side when driving on the right-hand bend.

*Please note: Some navigation systems provide incorrect directions or recommend taking the wrong autobahn exit. Alternatively, enter the house number 45, and upon arrival, follow the large sign on the left-hand side/opposite. In addition, please ensure that you only take exit number 34, “Wuppertal-Elberfeld”.
