Abstract
On the western entrance of Nablus lies the main junction of Haifa, Yafa and Tunis, which is considered as one of the most important junctions in the city. And due to the importance of this junction and the increasing traffic volume crossing it, congestion problems are observed which that the capacity of the junction after 20 years will not be enough to handle expected future traffic volume. This graduation project seeks a solution for such problem. Preforming studies to evaluate the current conditions was the first step. The second was to propose solutions and then select the best one based on specific criteria. The final task was to perform a detailed design for the selected alternative. The best solution for this problem was an overpass and an underpass. The most suitable choice of the overpass was between the eastern and western legs of Haifa Road with Tunis Roadway, and the most suitable choice for the underpass was between Tunis Road, Yafa Road, and the eastern leg of Haifa Road. Such configurations were designed according to suitable standards and specifications which involved many aspects such as geometric design and traffic design. The geometric design involves designing vertical and horizontal alignments and cross-sections, and the designs of traffic control devices involve signing and marking.
