February 6, 2023, Kahramanmara & scedil;-T & uuml;rkiye earthquakes caused widely scattered damage in southeastern T & uuml;rkiye. In this manuscript, liquefaction-induced failure of the Demirk & ouml;pr & uuml; bridge is discussed. The soil liquefaction triggering assessments and laboratory test results on surface ejecta suggested that the silty sand layer liquefied during the Pazarc & imath;k event. Back analyses of rotational failure surfaces revealed that the undrained residual strength and excess pore water pressure ratio values of the liquefied soil layer vary in the range of 17-30 kPa and 0.84 to 0.91, respectively. Comparisons revealed that the liquefaction induced instability would have been consistently predicted by available predictive models.
