This study presents the liquefaction potential analysis on the West Abutment of the New Kuning Palu Bridge. The New Kuning Palu Bridge was built to replace the Kuning Palu Bridge that collapsed in the 2018 Palu Earthquake. One year after the earthquake, a geotechnical investigation was conducted on the West Abutment plan. Liquefaction analysis was performed using the Idriss & Boulanger empirical method. Based on the study, the liquefaction potential in this area is classified as very high, with an IL of 46, and high severity, with an Ls of 69. Liquefaction can cause lateral displacement of 1.8 m and settlement of 0.25 m.
