Since May 2019 drivers on the A5 have been wondering about a 5 km stretch of road with overhead power lines amidst the motorway. What sounds a bit like science fiction is a pilot project for which Germany's Federal Ministry for the Environment is providing funding to the tune of 14.6 million euros.
The section of motorway selected here is one of Germany's highways with the heaviest traffic volumes. Every day some 130,000 vehicles travel this section of road.
This project involves a test section a good five kilometres in length between Langen/Mörfelden and Weiterstadt.
It is equipped with an overhead catenary line running in both directions above the motorway. This line supplies hybrid HGVs with electricity so they can recharge their batteries for the hybrid system.
