Interstate 675 Georgia

Interstate 675 Georgia
Stockbridge, GA ↔ near Conley, GA•11.04 miles

Overview

Interstate 675 (Georgia State Route 413) provides an alternate route to I-75 northward from Stockbridge in Henry County to the Perimeter Highway (I-285) in southwest DeKalb County. The freeway doubles as a commuter route for unincorporated suburbs in Clayton County while serving redevelopment of Fort Gillem to the west. I-675 appears rural with a wide median and only four lanes north from I-75 to the Double Bridge Road overpass, and six lanes from Forest Parkway north to I-285.

Road work scheduled for 2023 will modify the exchange joining Interstate 285 with Bouldercrest Road into a parclo interchange. Associated work adds a new distributor roadway from Bouldercrest Road to Interstate 675 south, separating weaving traffic movements from the Perimeter Highway westbound mainline.

History

Interstate 675 was applied to the route between I-75 at Stockbridge and I-285 in DeKalb County as approved by the American Association of State Highway and Transportation Officials (AASHTO) on June 17, 1975. Construction of I-675 commenced in December 1982, but was halted when a subcontractor defaulted on work in 1985, resulting in a new bidding process and other complications. These events delayed completion of I-675 until October 30, 1987. The freeway cost $61.6 million to complete.1

Construction of the I-75 South Metro Express Lanes included new ramps joining the managed lanes along Interstate 75 with the south end of I-675 at Stockbridge. Construction on the overall $176 million project kicked off in October 2014. A ribbon cutting ceremony preceded the January 28, 2017 opening of the toll lanes. They run 12 miles along I-75 southeast from SR 138 (Stockbridge Highway) to SR 155 (McDonough Road).2

The adjacent diamond interchange between I-285 (Perimeter Highway) and U.S. 23/SR 42 (Moreland Avenue) was modified with construction of the directional T interchange with Interstate 675. Ramps were added to consolidate movements from I-675 north and I-285 west to U.S. 23 and from U.S. 23 north to I-285 north and I-675 south.
