Archaeological crews made two separate discoveries of Iwi Kupuna on Friday, and Saturday.
The first was on Halekauwila near Keawe Street, where bones of at least two people were found.
Underneath cones and concrete roadblock is what the Oahu Island Burial Council says is the most significant find along the rail so far -- human remains in a fetal-like position.
Hinaleimoana Wong-Kalu with Oahu Island Burial Council said, "The significance of a flex burial means that most often it's pre-contact burial."
Pre-contact is the time before Captain Cook became the first European to visit the islands in 1778. The discovery could prompt the city to design the rail project so it avoids the site.
"What that does is place that burial in our jurisdiction, so the burial council almost always advocates for preservation in place," said Wong-Kalu.
Honolulu Authority for Rapid transportation CEO Daniel Grabauskas released a statement regarding these discoveries. In the statement, he said, "This work is being done years in advance of any construction in the area so that we can make any necessary design changes now."
Wong-Kalu said, "The Burial Council does have the wherewithal to say move the project or realign something, realign one of the columns."
Construction on the rail project was stopped in August after the Hawaii Supreme Court ruled the city should have completed the entire archaeological survey before beginning construction on the rail project.
"This is why the Burial Council had advocated for them to complete the archeological inventory survey prior to starting anywhere," said Wong-Kalu.
