The 2020 Petrinja earthquake had far reaching impact on the engineering linear networks, mostly flood protection embankments and road network. Liquefaction, a phenomenon where the saturated soil temporarily loses its strength and stiffness during intense ground shaking, caused significant failures, sinking, and tilting of the surface and near-surface infrastructure. The paper provides a valuable insight into the assessment of this phenomena, serving as a starting point for the development of resilient infrastructure and informing decision-makers on effective strategies for reducing liquefaction-induced damage along critical transportation routes. A comprehensive overview of methods which can be used for a simplified cyclic stress approach for the liquefaction assessment along the road transport network is given, including their advantages and shortcomings. An example comparing the in-situ CPT and MASW techniques for liquefaction resistance assessment is given for the location of Nova Drenčina, where many liquefaction-induced phenomena occurred after the mentioned Petrinja earthquake.
