In the past, the design of the roads was mainly concerning the links between the major cities and large towns in the West Bank. However, the access roads between villages were not considered as the allocated budgets were limited. Recently, as the number of population and vehicles increases dramatically, the existing relevant infrastructure should be developed to fulfill the new requirements.
One example for such roads is "Sanur – Qabatya" access road which is considered as an important link road is to be redesigned. The design and rehabilitation of such road will contribute in minimizing the travel time and distance from/to Jaba', Sanur and Nablus to Jenin governorates.
