Part of the Czech highway D1 is built over an undermined area of Ostrava, with mines closed since 1991. Soon after putting the highway into operation, it started to exhibit various faults. Highway deformations in late 2011 are observable from processing of limited set of 5 TerraSAR-X images using different methods. Detected deformations are probably due to longitudinal thermal expansion of the observed highway bridge as the discontinuities of deformations (Figure 4) directly fit with the locations of thermal dilation joints.
