A8 Motorway

The A8 project was the first of four pilot projects under the A-Model programme, involving the widening of heavily congested German motorways.

SPV General Manager Christian Diringer outlined the background to the A8 project.

„The A8 is a corridor belonging to the Trans-European Network (TEN) in Southern Germany.“

The challenge

SPV General Manager Christian Diringer continues:

„Some sections of the network were more than 60 years old and could no longer cope with heavy traffic volumes. In addition, some sections did not have an emergency lane and sight distances were hampered by crests. This section, located in Southern Bavaria, had traffic volumes of more than 100,000 vehicles per day, of which 11,000 were lorries exceeding 12 tonnes.“
