Route description

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.[2] The open section of Future I-85 is temporarily designated as State Route 108.

Interstate 685 is currently Interstate 85.

History

The designation was approved in 2010 at the request of the Alabama Department of Transportation (ALDOT) to use existing I-85.[2] Construction on the Montgomery Outer Loop started in early 2011, and the first part of it was completed in February 2016.[3] When done, the I-85 designation will be shifted to the Outer Loop, and the existing freeway will become just I-685.[4] This will be the first auxiliary interstate of Interstate 85 that starts with a six.[5]

Exit list

The entire route is in Montgomery, Montgomery County.
