Fürth to Austria There are six lanes between Kreuz Fürth/Erlangen and Kreuz Nürnberg while the remaining section towards the Austrian border only has two lanes in each direction. Special Between Cologne and Frankfurt an ICE high-speed railway line (300 km/h) closely follows the A 3's route. Two sections in the Frankfurt area are equipped with a special kind of facility to allow a temporary release of the emergency lanes during the rush hour. The section between Hanau and Offenbacher Kreuz and also the section between Kelsterbach and Mönchhof-Dreieck have this facility, so that a further lane for each direction can be opened.
