Major Regional Employer Travel Routes
1. Commuting to Oak Ridge National Laboratory (ORNL)
Most ORNL employees reside in Hardin Valley, Farragut, or Oak Ridge proper. Traveling north along Pellissippi Parkway (SR-162) provides a direct, high-speed 4-lane route with light congestion outside the Solway interchange during shift change hours (7:00 AM – 8:00 AM).
