Narrative Description of Project: 
The Pan Arab Highway is an East – West dual carriageway of 62 km length, extending from the southeast of Beirut to the Lebanese border with Syria, forming a vital artery of the Lebanese Transportation Network with a major linking function between Lebanon and the Arab Countries.
