Interstate 85 (I-85) is a part of the Interstate Highway System that runs from Montgomery, Alabama, to Petersburg, Virginia. In Alabama, the Interstate Highway runs 80.008 miles (128.760 km) from I-65 in Montgomery north to the Georgia state line near Valley. I-85 is the primary highway between Montgomery and Atlanta. The Interstate also connects Montgomery with Tuskegee, Auburn, Opelika, and, indirectly, Phenix City and Columbus, Georgia.

I-85 begins at a six-ramp modified directional-T interchange with I-65 southwest of downtown Montgomery. In addition to the ramps to and from I-65, the terminating Interstate's dual carriageways continue west a short distance and become Day Street; the interchange also includes a ramp from southbound I-65 to Day Street and from Day Street to northbound I-65. I-85 heads east toward downtown Montgomery as an eight-lane freeway. The highway has a pair of half-diamond interchanges with Court Street (northbound exit, southbound entrance) and Union Street (southbound exit, northbound entrance). The one-way pair of Arba Street and South Street serve as frontage roads for the northbound and southbound lanes, respectively, along the southern edge of downtown. The interchanges provide access to the Alabama State Capitol and Alabama State University. Southeast of downtown Montgomery, I-85 has a pair of half-interchanges with Forest Avenue (northbound exit, southbound entrance) and Mulberry Street (southbound exit, northbound entrance).
