Onu-Koro Highway

The Onu-Koro Highway was an underground tunnel system that connected Onu-Wahi to Ko-Wahi.

History
The Onu-Koro Highway was constructed during the Dark Time as a safe means of transport between the two villages. However, due to the darkness and isolation of the tunnels, they eventually fell out of disuse.

They were used by Takua and Jaller during their search for the Seventh Toa. In them, Takua encountered Teridax, who convinced him to abandon his quest of finding the Seventh Toa, although Jaller continued.

The highway was later destroyed by the Bohrok swarms after they were reawakened. The remainder of the tunnel was destroyed when Mata Nui awakened.
