A new bike route will link Chattanooga to Atlanta.

U.S. Bike Route 21 will be 160 miles long. It's one of the first U.S. Bicycle Routes approved by the American Association of State Highway and Transportation Officials recently.

The Georgia Department of Transportation has been coordinating with Tennessee to designate USBR 21, which will eventually connect Atlanta to Cleveland when it is complete, according to a news release.

The route terminates in Atlanta and connects via the renowned Silver Comet Trail and scenic country roads to Chattanooga, the Georgia DOT said.

USBR 21 begins in downtown Atlanta at the Five Points MARTA Train Station, which accesses the Hartsfield Jackson International Airport, providing an easy connection to the route for international cyclists. The route leaves Atlanta on iconic Peachtree Street, then connects to the Silver Comet Trail, a scenic rail-trail that extends to Alabama. USBR 21 heads north from the Silver Comet Trail in the city of Cedartown. Two-lane country roads bring bicyclists through northwest Georgia to Chickamauga, then to St. Elmo and eventually, Finley Stadium, where the route ends.

The route consists of trails and roads with new signage and markers.

Two spur route--USBR 321 and USBR 52-- will connect cyclists to other destinations in Northwest Georgia and connect back to the main route. USBR 321 takes cyclists through the Chickamauga and Chattanooga National Military Park. USBR 521 connects to Mountain Cove Farm.
