The Foothills Parkway has been in the works for some 75 years and is probably another 20 years to completion. The southern most 17 miles running from US 129 at the Chilhowee Lake to US 321 at Walland was completed in 1966 and is quite spectacular. The next phase of 16 miles was opened in December of 2018. This extension runs 17-miles from  US 321 in Walland to Wears Valley.
