[1] In 1862, brothers Charles and James Salisbury surveyed the first 6 miles (9.7 km) of this road, noting it was marked by parallel earthen banks almost 200 feet (61 m) apart and led from the Newark Earthworks.
[1] In the 1930s, the area was surveyed by plane, revealing traces of the road extended for 12 miles (19 km) toward the Hopewellian center of present-day Chillicothe.
Additional examination of the area with the new sensing technology of LiDAR (Light Detection And Ranging) adds confirmation to this finding and suggests a way to gain more evidence.
South of there, the projected path of the Hopewell Road passes through fields toward Millersport, Licking County, Ohio.
Evidence from early accounts and 1930s aerial photography suggests that the Hopewell Road may continue south of Ramp Creek, and a cultural resource management study provides equivocal, yet suggestive evidence of the earthwork south of Ramp Creek.
