A3 autobahn, Frankfurt - Nuremberg
Upgrading with additional lanes
The A3 autobahn forms part of the trans-European transportation network. It connects the Benelux states with southern Europe, and, within Germany, connects Bavaria with numerous cities along the Rhine. It was built over 50 years ago as a four-lane autobahn, but has become heavily over-trafficked in recent years with traffic volumes of up to 100,000 vehicles per day. This resulted in increasing numbers of accidents and much traffic congestion. The upgrading project, with the number of lanes increasing to six between the junction at Aschaffenburg and the autobahn crossing at Biebelried (a distance of approximately 11 km), enabled this stretch of highway to efficiently meet current demands.
