Abstract:Over Dimensional Cargo (ODC) transit poses special logistical and operational issues because of its non-standard weight, dimension, and handling specifications. This research examines the main causes of ODC transportation time delays, with a special emphasis on port and road transit utilizing the Non-Vessel Operating Common Carrier (NVOCC) model. Careful planning is necessary for ODC shipments, including route surveys, obtaining permits, using specific equipment, and adhering to regulations. According to the report, there are inefficiencies in the current systems that cause major delays and higher operating expenses. These inefficiencies include complicated documentation, bureaucratic obstacles, infrastructure restrictions, and fragmented cooperation among stakeholders. The study assesses best practices in packaging, securing, and delivering ODC by examining a variety of cargo types, such as huge structures, offshore components, and heavy machinery. Additionally, it evaluates how technical, infrastructure, and environmental issues affect the transportation of freight. Through risk management techniques, contingency planning, and route feasibility studies, a particular focus is focused on the role that logistics service providers play in guaranteeing ODC shipping that is safe, fast, and compliant. The project provides solutions through qualitative and quantitative analysis, including the use of real-time tracking technology, simplified permitting procedures, improved safety measures, and integrated digital platforms for information sharing. The study's ultimate goals are to increase overall effectiveness, cut down on delays, and support environmentally friendly logistical techniques. Logistics companies, legislators, and industry participants working to maximize ODC transportation and satisfy the rising need for specialized cargo movement in industries like manufacturing, energy, and construction should use the findings as a guide
