Designing the splitting of a road section (CW46) over 5km

Our project concerns the splitting of the CW46 between Sidi Maarouf and Hassi Bounif in the wilaya of Oran, it begins at pk 00+0000m and ends at pk 05+356 m, this section to be studied extends over a length of 5,356 km and vehicle a significant average daily traffic estimated at around 9000v/d.The route consists of maintaining the existing roadway as much as possible and doubling it:¿ The percentage of heavy goods vehicles is 25%, according to a last count carried out in 2014.¿ The project route is located in a flat terrain, and is characterized by medium windings (E2), and medium gradients. It is classified in category (C2) and the base speed of the project is estimated at 80 km/h.The road runs parallel to the railway, buildings, agricultural land as well as crossing with ring road 2 from PK 4+221.645 m to PK 4+267.207 m. They are considered as constraints which pose a difficulty.It is connected to several towns and villages such as Sidi Chahmi and Sidi Okba Zaouïa Bel Kaidiä also it is used as a link between these towns and villages with the city center of Oran.
