Obi-Wan Kenobi along with Anakin Skywalker are in pursuit within a skytunnel. A tram tunnel, otherwise called a skytunnel, served as a transportation route via a tunnel that went through a structure, facilitating vehicle movement across the ecumenopolis world that was Coruscant.
The origin of skytunnels often stemmed from instances where a skyway, previously used for traffic, was obstructed due to the construction of a building by a strong, yet unaware, corporate entity. They additionally provided a means of routing traffic above zones of substantial financial or governmental importance, demanding heightened security.
