<![CDATA[Bridge infrastructure projects in Indonesia often face transport safety challenges due to overlapping construction areas with active traffic lanes. This study aims to identify waste categories in bridge projects and analyze their implications for transport safety. A mixed-methods approach was employed, combining literature review, questionnaire surveys of 197 respondents (contractors, consultants, and field workers), expert interviews, and field observations. The research instrument was tested for validity (r > 0.3) and reliability (Cronbach's Alpha = 0.872), while risk analysis was conducted using Failure Mode and Effects Analysis (FMEA) with parameters of Severity, Occurrence, and Detection. The findings indicate that all eight Lean Construction waste categories were identified. Defects/Rework had the highest perceived risk for workers (mean = 4.1), while Transportation ranked highest for the public (mean = 4.2). FMEA analysis confirmed the highest RPN values for Defects/Rework (381), Transportation (364), and Inventory (333) all classified as high risk. Mitigation strategies focused on quality improvement, logistics optimization (including Just-in-Time), and managerial reinforcement through daily huddles and visual management. This study concludes that Lean Construction is not only effective in reducing waste but also serves as a strategic approach to enhancing transport safety in bridge projects. ABSTRAK (Bahasa Indonesia) Proyek infrastruktur jembatan di Indonesia sering menghadapi tantangan keselamatan transportasi karena tumpang tindih area konstruksi dengan jalur lalu lintas aktif. Penelitian ini bertujuan mengidentifikasi kategori waste pada proyek jembatan serta menganalisis implikasinya terhadap keselamatan transportasi. Pendekatan mixed methods digunakan, menggabungkan studi literatur, kuesioner terhadap 197 responden (kontraktor, konsultan, dan pekerja lapangan), wawancara pakar, serta observasi lapangan. Instrumen penelitian diuji validitas (r > 0,3) dan reliabilitas (Cronbach's Alpha = 0,872), sedangkan analisis risiko dilakukan dengan Failure Mode and Effects Analysis (FMEA) menggunakan parameter Severity, Occurrence, dan Detection. Hasil penelitian menunjukkan bahwa delapan kategori waste Lean Construction teridentifikasi. Defects/Rework memiliki persepsi risiko tertinggi bagi pekerja (mean = 4,1), sementara Transportation tertinggi bagi publik (mean = 4,2). Analisis FMEA mengonfirmasi nilai RPN tertinggi pada Defects/Rework (381), Transportation (364), dan Inventory (333) semua tergolong risiko tinggi. Strategi mitigasi difokuskan pada peningkatan mutu pekerjaan, optimalisasi logistik (termasuk Just in Time), serta penguatan manajemen melalui daily huddle dan visual management. Penelitian ini menyimpulkan bahwa Lean Construction tidak hanya efektif mengurangi pemborosan, tetapi juga menjadi pendekatan strategis untuk meningkatkan keselamatan transportasi pada proyek jembatan]]>
