Stock Photo - 11 November 2021, Saxony, Rötha: In the meantime, the future course of the A72 can be clearly seen next to the existing federal highway 95 near Rötha. The last construction section 5.2 is also the most complicated of all. Almost the entire route runs on the site of a former open-cast mine and must be compacted extensively beforehand. So far, almost 2 million cubic meters of earth have been moved and a good 14,000 of these concrete blocks, known as Lego bricks, have been placed.
