Highway 66


Tennessee Highway 66
Great Smoky Mountains Parkway
Improvement Project

If you’ve ever driven from I-40 to Sevierville, Pigeon Forge or Gatlinburg in the last 15 years, you have come to expect congestion along State Route 66, The Great Smoky Mountains Parkway. The Tennessee Department of Transportation was able to accelerate funding to improve this important route with funds from the American Recovery and Reinvestment Act (ARRA). The entire project from I-40 to downtown Sevierville will widen the existing highway from 4-lanes to 6-lanes improving congestion and enhancing safety for the traveling public.

Over 9 million people visit the Great Smoky Mountains National Park each year, making it the most visited national park in the country.
