conditioning system. Meanwhile, Mohammed Idrees, deputy dean of King Fahd Hajj Institute at Um Al-Qura University and head of the institute's Jamrat Bridge design team, said the project would reduce the density of pilgrims at the entrances of the bridge. The ground and first level of the bridge are designated for pilgrims coming in from east Mina, who represent the majority. The second level is for pilgrims coming in from Makkah side, the third from north Mina and the new pilgrim residences in the tent city, and the fourth level is for pilgrims coming in from south Makkah through King Abdul Aziz Road. "This way we can fragment the density of the pilgrims before they reach the throwing site," Idrees told Arab News.
