The Israeli West Bank barrier is a separation barrier being constructed by the State of Israel along and within the West Bank. Upon completion, the barrier’s total length will be approximately 760 kilometres (470 mi). The barrier is a fence with vehicle-barrier trenches surrounded by an on average 60 metres (200 ft) wide exclusion area (90% of its length), and an 8 metres (26 ft) tall concrete wall (10% of its length). The barrier is built mainly in the West Bank and partly along the 1949 Armistice line, or "Green Line" between Israel and Palestinian West Bank. 12% of the West Bank area is on the Israel side of the barrier.
