The U.S. Congress has mandated funding for six parkways:
- The Chickamauga-Chattanooga National Military Park Bypass
- The Baltimore-Washington Parkway
- The Cumberland Gap National Historic Park Tunnel
- The George Washington Memorial Parkway
- The Natchez Trace Parkway
- The Foothills Parkway
These parkways offer exceptional travel experiences for Americans and foreign visitors. For example, the Natchez Trace Parkway, completed in 2006 after 67 years of construction in Tennessee, Alabama, and Mississippi, is now considered one of the most scenic and beautifully designed parkways in America, and is designated as an "All American Road" scenic byway.
Five of the six parkways mandated by Congress have been completed. The Foothills Parkway is complete with the exception of a series of bridge structures, sometimes referred to as "The Missing Link."
Because of the missing bridges, only three segments, totaling 22.5 miles of the entire 72-mile corridor, are currently open to the public. The map below shows the segments that have been completed, as well as the segments that cannot be accessed due to the bridge construction.
