The Le-Koro Highway was an underground highway that connected Le-Koro with Onu-Koro. TuragaWhenua approved its construction, but progress was slow and the Guildmasters became impatient. The project fell months behind schedule due to the lack of lighstones in the village. The Onu-Koro Council complained that without the highway, the other villages were unable to trade with Onu-Koro. When the source of light in the city was repaired by Takua, work resumed and Taipu broke through and finished the highway, opening Onu-Koro up to trade again. The highway was destroyed when the Bohrok were awakened again.
