The National Interstate and Defense Highways Act of 1956, which created the interstate highway system, also dealt a blow to communities across the nation including Columbus.

Neighborhoods housing African Americans were the hardest hit.

In order to study what was lost, a team of Ohio State University researchers is using 3D technology to recreate the communities of the past.

Today on Tech Tuesday, we are taking a look at what we can learn from the Ghost Neighborhoods of Columbus.

Harvey Miller, Bob and Mary Reusche Chair in Geographic Information Science and Leader of the Ghost Neighborhoods of Columbus Project
