The Streichgrund viaduct is a 450 m long girder bridge . It is located on the BAB 71 in the Thuringian Forest between the Ilmenau -Ost and West junctions and spans a valley with the natural biotope of the Streichtich, the Wiesenbach and the L2272 between the Ilmenau districts of Unterpörlitz and Heyda at a maximum height of 27 m.

The bridge is curved in plan, has a transverse gradient of 2.5% and rises towards Schweinfurt. It was built with two separate superstructures between 2000 and 2002. The cost was 29 million DM.
