Archaeologists will begin their second week of excavation in the search for possible mass graves from the 1921 Tulsa Race Massacre on July 20.
On Friday, they found an old road that used to run east to west.
The trench where they discovered the road is about 60-feet long and 10-feet deep.
Last week, archeologists unearthed many artifacts like bottles, nails, bricks and even a shotgun shell - which experts say was not connected to the race massacre.
They also found animal bones but no human remains yet.
Today they'll begin a coring technique, which is taking soil samples. The city and experts will give an update on Tuesday.
The city is also live stream the test excavation work.
