started with the earthworks for the ramps. But these enormous masses of earth were then overgrown and unused for well over 15 years. Only in 1997, the highway triangle itself and a few kilometers A 1 was completed to the junction Daun, the rest of construction then rested but initially again. Continuation The continuation from Trier to Saarbrücken was tackled in the 1970s and early 1980s. First emerged in the 1970s in the context of a full expansion of 1960 and 1964 as federal highway 268 or 327 built single-lane and 1969 in A 171 umgewidmeten track sections Saarbrücken-Riegelsberg and Illingen-Eppelborn. Originally, this federal road should continue to Hermeskeil and meet there on the B 408 Koblenz-Trier-Landstuhl. In the plans from the 1930s, a Tangierung the Saarland latter was not provided, the realized planning with the triangle Nonnweiler therefore deviates significantly from the pre-war planning. The section Riegelsberg-Saarbrücken, was indeed developed in 1960 as a federal highway four lanes, but originally had no structural separation, which accidents due to wetness on the winding route were common. A central plank was therefore only retrofitted in the course of the upgrade. This explains the unusually narrow profile of the motorway in this area, which also does not have streaks here. Coming to the end of the 1970s, the A 1 between Saarbrücken and Reinsfeld was completed in sections, was missing only the gap between the Reinsfeld and the triangle Moselle valley. This 20 km long track with two larger bridge structures (Fellerbach and Molesbachtal bridge) was completed in 1983, making the A 1 between Daun and Saarbrücken completely passable. Reunification With the German reunification, it had accounted for the double numbering between the triangle Vulkaneifel and Trier. Since the section Dernbach-Wetzlar, A 48 should not be realized, the name of this was reduced to the route triangle Vulkaneifel-triangle Dernbach. The already built piece northwest of Trier to the Luxembourg border was renamed A 64, as well as the already finished sections in Hessen received new numbers (A 480 and A 5). On some older signposts, however, this double numbering still exists. 2000s In the early 2000s, both the continuation from Oldenberg in Holstein to the north and the gap closure in the Eifel between Blankenheim and Daun were planned and partially realized. On 20 December 2002 the section from the former motorway south to north of Oldenberg in Holstein was cleared by
