Onu-Koro Highway

"Takua, Jaller, and Pewku stopped beside a small tunnel entrance dug out of an icy mountainside."

- Narrator, Mask of Light

The Onu-Koro Highway was an old and abandoned tunnel on Mata Nui, connected Ko-Wahi to Onu-Koro.

History
The tunnel in which the highway was located was built by the Matoran to service transportation between the villages. Due to the increased number of infected Rahi attacks in the extreme darkness of the tunnels, the highway fell out of use.

It was re-discovered by the Matoran Takua and Jaller during their quest to find the seventh Toa. While playing around with some biolumniscent plants he found in the tunnel, Takua got lost and met Makuta Teridax, in the form of a pair of great glowing crimson eyes in the darkness. The Makuta tried to convince him to abandon the quest and leave Jaller, which shook Takua's confidence and incited him to do as Teridax requested. As the Av-Matoran and Pewku made their way towards Onu-Koro, Jaller veered off the main path, following the direction of the glowing Kanohi Avohkii.

The tunnel was later cleared by the reawakened Bohrok swarms.
