Narrative Description of Project:
This motorway project begins at Qalamoun, just South of the City of Tripoli and extends northwards to the Syrian border. It bypasses the city of Tripoli to the East and continues North, parallel to the existing coastal highway, until Zouk interchange, where it branches in two. One branch goes to the Syrian border at Tall Hmaira on the route to Homs, the other to the Syrian border at Arida on the route to Latakia. The motorway has a total length of approximately 55 Km.
Description of Actual Services Provided:
The economic feasibility study comprised a detailed study of the corridor, which included roadside O-D surveys and traffic counts. A travel model was calibrated which enabled testing various scenarios. The travel forecast was based on expected growth in parallel variables and the expected economic conditions, locally and regionally. The improvements required on the exiting road, whether the motorway was built or not, were determined.
The scope included calculation of the vehicle operating cost (VOC) for various vehicle types and road conditions, and the value of time of drivers and passengers. These calculations were necessary to calculate the benefits of various alternatives.
The construction costs were based on a detailed bill of quantities and unit prices were based on experience from recent contracts. Periodic and routine maintenance costs were also calculated.
The scope of work included studying the environmental impact of this project on its corridor. Noise emission and accidents forecasts were simulated, with and without the proposed projects. An environmental management plan was proposed for the construction phase and beyond.
