Why buyers look at Clayton
Clayton is a town in western Johnston County, east of Garner along I-40. It had 26,307 people in the 2020 census, and recent Census estimates put it above 30,000.
Novo Nordisk already runs two manufacturing facilities in Clayton. In June 2024 it announced a $4.1 billion expansion here with 1,000 new jobs, with major construction phases expected to finish between 2027 and 2029. Grifols and Caterpillar are also large local employers.
Road names around Clayton changed in 2025. About 10 miles of the US-70 bypass between I-40 (Exit 309) and the US-70 Business interchange became I-42. Old US-70 Business became US-70 again, named Clayton Boulevard near the county line, and NC-42 in this area was renumbered NC-36. Older listings and maps may still use the former names.

History
From Stallings’ Station to Clayton
The town grew along a road cut around 1770 by Governor Tryon’s troops marching from New Bern to Hillsborough. When the North Carolina Railroad arrived nearly a century later, the depot was in the home of Sarah Stallings, and the stop was called Stallings’ Station.
The name changed to Clayton after about three years, and the town was incorporated in 1869. Cotton, watermelons, and tobacco were the early crops. Eight Clayton properties are now on the National Register of Historic Places, including the Clayton Historic District and the Cleveland School.
