WEARS VALLEY, TN (News Sentinel) — They call it Bridge 2. That's it, just Bridge 2.

It's an engineering marvel with a deceptively simple name, and with a price tag of $25.7 million, it didn't come cheap.

On Monday, officials with Great Smoky Mountains National Park held a ribbon-cutting on the Foothills Parkway to celebrate the completion of Bridge 2, one of nine bridges that will eventually span the rugged 1.6-mile section of the parkway between Walland and Wears Valley known as the "Missing Link."

Congress authorized the Foothills Parkway in 1944 as a 72-mile scenic highway that would showcase Great Smoky Mountains from the outside looking in.
