Interstate 685 (I-685) is the designation for a future Interstate Highway in the U.S. state of Alabama. When completed, it will connect I-65 in downtown Montgomery to I-85 in the eastern suburbs of Montgomery.

Route description[edit]

Currently, I-685 has been approved by the American Association of State Highway and Transportation Officials (AASHTO) to be co-signed with the current I-85 from its current southern terminus at I-65, to the future location of the Montgomery South Bypass on which I-85 will be rerouted.[1]


The designation was approved in 2010 at the request of the Alabama Department of Transportation (ALDOT) to use existing I-85.[1] Construction on the Montgomery Outer Loop started in early 2011, and it was expected at the time to take two or three years to complete. When done, the I-85 designation will be shifted to the Outer Loop, and the existing freeway will become just I-685.[2]

Exit list[edit]

The entire route is in Montgomery, Montgomery County.
