NC: Clayton Bypass Project

“We are so very pleased that the project was completed ahead of schedule. It is such a benefit to the entire County in terms of traffic safety and economic impact. It is regarded as one of the most scenic drives through our region.”

The Clayton Bypass (U.S. Highway 70) is a new 10.7-mile, four-lane divided freeway from I-40 to US-70 in Johnston and Wake counties. The project included building 22 new bridges, and four new interchanges with major arteries, demolishing three existing bridges, and widening two miles of both eastbound and westbound I-40. Heavy traffic flows and multiple environmental concerns led to the use of numerous innovative techniques, intelligent transportation systems and materials, including turbidity monitors, temporary work bridges, and the state’s first fully automated speed detection system. Speed sensors located throughout the project allowed dynamic message signs to display real-time travel information, including estimated drive times. Motorists can now bypass 11 stoplights, saving between 15 to 30 minutes in travel time. It has also immediately eased workday commutes for 29,500 vehicles. A close working relationship between contractors and NCDOT allowed this major construction project to be completed one year ahead of schedule. It has improved traffic flow both through and around the town of Clayton, and was designed to preserve important environmental areas in the Neuse River and Tar River Basins.
