Wake County, NC

This new location, four-lane divided roadway that intersects with I-540 and ties into Davis Drive improved traffic flow for commuters to Research Triangle Park’s high-tech workplaces. Research Triangle Foundation hired CALYX to provide contract administration, recording and calculating of quantities, sampling and testing, construction inspection and surveying services for this project. More than 72,500 cubic yards of unclassified excavation and roughly 3,000 cubic yards of shoulder borrow were moved at the site. The project spans a tributary of Kit Creek, an environmentally sensitive area, where a 145-foot, dual 72‑inch reinforced concrete pipe culvert was built.
