A Certain Iron Bridge

The iron bridge as seen in the twelfth episode of the anime

A Certain Iron Bridge (とある鉄橋, Toaru Tekkyō^?) is a notable landmark of Academy City in the Toaru Majutsu no Index series that can be found in the School District 7.

Principles

Located in the Seventh School District, this iron bridge is the first major Academy City landmark in Toaru Majutsu no Index. The bridge spans over a river, with a length of around 150 meters.

There is a railway line that runs on the riverbank beneath this bridge, and some cargo seems to be stored in the area.

Chronology

Index Arc

Main article: Index Arc

On July 19th, fleeing from a large group of delinquents after seeing some of them harassing Misaka Mikoto and interfering in an attempt to save them from her wrath (revealed in the Level Upper Arc to be a misunderstanding, as Mikoto was actually attempting to gather information on the Level Upper from them) only to find there were too many for him to handle, Touma ended up on the bridge, where Mikoto caught up to him after taking care of the delinquents. During the subsequent clash, Mikoto called down huge lightning strikes, rendering more than 80% of the city's electric appliances inert.

Misaka 9982 ran to the area beneath this bridge during the 9982nd Level 6 Shift experiment in order to lead Accelerator towards one of the mines she planted. During the conclusion of the 9982nd Level 6 Shift experiment, Mikoto fought and failed to defeat Accelerator in the area beneath this bridge.

This bridge was where Kamijou Touma found Misaka Mikoto after she attempted to manipulate the data from the Tree Diagram information reception center. Touma stopped Mikoto from heading to her death on this bridge, and took on Mikoto's lightning attacks before heading off to fight Accelerator.

Accelerator lied to Kamijou Touma when they talked over the phone, and told the latter to head to this bridge to meet Last Order. Touma hurried to this bridge and met Vento of the Front for the second time, witnessing the completion of the Imaginary Number District's expansion from here.

The two opposing groups of Transcendents facing one another on the bridge.

On the night of January 6th, the bridge was the site of a clash between Transcendents of the Bridge Builders Cabal, one group having fought alongside Touma against "CRC" and looking to help him reach the revived and unstable Alice Anotherbible, while the other group of opportunists had scattered after "CRC" had seemingly killed Alice and returned on learning she was alive again, looking to preserve their own power and intending to prevent the meeting.
