1.The length of the proposed road was 18210.88 m according to the data of the Ministry of Municipalities, 24 m width with two corridors, and the coordinates

2.The TIN is the basis of the accuracy of the roads' coordinates, because it is

3.All horizontal and vertical road elements are defined through the CIVIL 3D program, facilitating and accelerating the design process in accordance with

4.Four horizontal curves and three vertical curves were proposed for the proposed road, according to the topography of the earth, which required this

5.The design of the roads using Civil 3D and GIS in all its components makes the design process highly efficient through the speed of time, little effort, and low

6.Civil 3D has all the international standards used in road design and has all the tools that can easily define all design elements for roads and export it to GIS.

7.The program provides us with longitudinal and cross sections that show the change in ground and construction line levels very accurately, which facilitates

8.The volume calculated by using the program is very precise. The earthwork produced by the pieces can be used to bury the areas that need to be buried. The construction line chosen to represent the proposed road level was chosen

9.The road data exported to the GIS program has created an integrated road database. This database can be performed on any kind of spatial analysis or
