For the size of traffic of the trucks transporting different types of commodities to and for ports of Basrah, passing on the internal routes of Al-Amarah city, and for the exceeding of congestions inside the city, and to reduce the continous maintenance on these roads, then it was necwssary to contruct a new road to connect the two roads (Baghdad- Amarah) and (Basrah- Amarah). According to the basic design of Amarah city, and the traffic study and the study of the technical and economical utility prepared by Al-Hadatha Engineering Consultation company including the construction of a main bridge on Tigris and three intersections ( upper-bridges) with the intersected roads (note image No.1 which illustrates the suggested route, main bridge and intersections):- Amanah - Kut Route- Amarah -Batra Route- Amarah - Basrah Route As shown in the details on the study listed later in the study, the purpose of the study is to evaluate the present status of the existing intersections on (Amarah-Basrah Route) and determine level of performance, delay rate and satisfaction degree. Calculate the traffic sizes (present and future) which will use the open road. Determine the number of passes of the suggested road for all the bridged intersections, and bridges to show their level of performance. The future life of the bridged intersection will be specified as (20 years), and all the analytical calculations aim at giving an approximate picture to the future status of traffic congections, and using the annual increase rate of vehicles throughout this period.
