The new bridge (designed by Dar Al-Handasah and constructed by the Saudi Binladin Group) contains a wider column-free interior space and expanded jamrah pillars many times longer than their pre-2006 predecessors.
Additionally, Saudi authorities have issued a fatwa decreeing that the stoning may take place between sunrise and sunset, rather than at the mid-day time that most pilgrims prefer.
Keith Still, professor of crowd science at Manchester Metropolitan University was consulted in 2004 by the Saudi authorities on designs for the new Jamarat bridge, to ease the bottleneck in front of the pillars.
Edwin Galea of the Fire Safety Engineering Group at the University of Greenwich pointed out that the 500,000 people per hour that the Jamaraat Bridge could deliver was equivalent to the largest ever football crowd every 24 minutes, or the population of Germany in a week; he suggested that spreading the Hajj over a longer period was a possible solution.
