Each tube contains two lanes of traffic and is equipped with safety features designed to handle emergencies. Authorities completed a massive expansion project, constructing a entirely new parallel tunnel to replace the older structure.

This new tunnel, opened recently, incorporates the latest safety and ventilation standards.
