1372-448: The chief reasons assigned by urban planners for skywalk development are decrease of traffic congestion , reduction in vehicular air pollution and separation of people from vehicular noise . A number of cities (for example, Spokane, Washington) have given intricate analysis to skywalk systems employing computer models to optimize skywalk layout. There is debate about the negative impact on urban areas of skyways. Robertson (1988) noted

1421-472: The city government, connecting between privately run rail stations or other transport with their own footbridges, and run many kilometers. Skyways usually connect on the first few floors above the ground-level floor, though they are sometimes much higher, as in Petronas Towers .

There are also 6 heavy-duty elevators for utility. The lift system information of

2254-549: The twin towers of the World Trade Center in New York City) showed that the bridge would not be useful if both towers need to be emptied simultaneously, as the capacity of the staircases was insufficient for such an event. Plans thus call for the lifts to be used if both towers need to be evacuated, and a successful drill following the revised plan was conducted in 2005. There is a two hinged arch that supports

2303-455: The two towers during high winds. The bridge is 170 m (558 ft) above the ground and 58.4 m (192 ft) long, weighing 750 tons. The same floor is also known as the podium, since visitors going to higher levels have to change elevators here. Dynamic analyses were performed and iterated to support the final design by studying the structural behavior of the twin towers to time-varying loads such as earthquakes and wind. The skybridge

2352-486: The way to level 86. Visitors are only allowed on the 41st floor as the 42nd floor can only be used by the tenants of the building. The skybridge also acts as a safety device, so that in the event of a fire or other emergency in one tower, tenants can evacuate by crossing the skybridge to the other tower.
