Interstate 675 Georgia

 

Routing

Interstate 675 (Georgia 413) is an alternate route to Interstate 75 between the Perimeter Highway (Interstate 285) in south Dekalb County and the Clayton and Henry County suburbs of the Atlanta metropolitan area.

History

Interstate 675 was originally planned to be much longer, as part of a proposed north/south highway that would have extended north of Interstate 285 into the Atlanta city limits. The highway was to have joined the south end of the U.S. 19/Georgia 400 freeway to the north at the beltway, from the current northern terminus. One-third of this highway was constructed as the tolled extension of Georgia 400. Maps originally showed Interstate 675 as part of Georgia 400 as well. Proposed Interstate 420 was purged from the Atlanta highway plan around the same time as the Georgia 400 connection between the toll road and Interstate 675.

Construction of Interstate 675 commenced in December 1982. Work was halted when a subcontractor defaulted on work in 1985, resulting in a new bidding process and other complications. These events delayed completion until October 30, 1987. The freeway cost $61.6-million to complete.1

Highway Guides

Southern Terminus - Interstate 75 - near Stockbridge, Georgia
Perspective from Interstate 675 south
Like the southern terminus of Interstate 985, Interstate 675 concludes in a "Y" interchange. This means that traffic movements are limited to Interstate 75 north to Interstate 675 north and Interstate 675 south to Interstate 75 south. Therefore motorists wishing to access Interstate 75 northbound must utilize Georgia 138 west to Interstate 75 Exit 228 one mile to the west. Photo taken by Chris Patriarca (02/23/03).
Interstate 675 southbound at Exit 1/Georgia 138 to Stockbridge. This is the final interchange of the freeway, with motorists continuing southbound defaulted onto Interstate 75 southbound. Photo taken by Chris Patriarca (02/23/03).
End Interstate 675 shield, posted at the Exit 227 interchange of Interstate 75. 60 miles separate this location from Macon via Interstate 75. Photo taken by Chris Patriarca (02/23/03).

Two miles south of the Interstate 75/675 split is the first guide sign of Exit 227. This particular panel indicates the main function of the 3-digit Interstate: a connection to Interstate 285 east/north. Photo taken by Chris Patriarca (02/23/03).
Two lanes are available for Interstate 675 northbound motorists. Interstate 75 meanwhile retains six lanes through the Exit 227 interchange. Interstate 75 overall is six lanes or more throughout the Peach State Photo taken by Chris Patriarca (02/23/03).
0.25 miles south of the Interstate 675 split, control cities of Augusta and Greenville for Interstate 285 northbound are applied. Photo taken by Chris Patriarca (02/23/03).
In case one was wondering from where Augusta and Greenville came, this auxiliary overhead advises. The panel also warns that the right-hand lane is now exit-only. Photo taken by Chris Patriarca (02/23/03).
The northbound beginning of Interstate 675 occurs here. Interstate 75 northbound continues another 20 miles into downtown Atlanta. Photo taken by Chris Patriarca (02/23/03).

Now on northbound Interstate 675, the first interchange is Exit 1, Junction Georgia 138 to Stockbridge. Photo taken by Alex Nitzman (05/28/05).
The first reassurance shield for Interstate 675 north is posted on the left side of the freeway after the split from Interstate 75. Photo taken by Alex Nitzman (05/28/05).
Northern Terminus - Interstate 285 - near Conley, Georgia
Perspective from Interstate 675 north
Four miles separate the terminus interchange (Exit 11) with the last mainline interchange (Exit 7) on Interstate 675. This photograph looks at a diagrammatical overhead for Interstate 285 at the Cedar Grove Road overpass, one mile south of the conclusion of Interstate 675 north. The original button copy signage of the one-mile guide sign is also shown -- note the removed sign lighting fixtures as well as the old exit number. Photos taken by Chris Patriarca (02/23/03) and Jim K. Georges (07/99).
Drawing to within one-half mile of the conclusion of Interstate 675 northbound. Note that Interstate 285 westbound utilizes just Atlanta as a control city. This is because traffic using Interstate 285 westbound generally is Atlanta bound traffic from the southeast suburbs of which Interstate 675 serves. Again the original button copy signage shows the signage before the conversion to mileage-based exit renumbering. Photos taken by Chris Patriarca (02/23/03) and Jim K. Georges (07/99).
The END Interstate 675 shield follows. It is posted just past the sign bridge Pictured in the above two photographs. Photos taken by Alex Nitzman (05/28/05).
Motorists are again reminded of the connections Interstate 285 makes with Interstate 20 east for Augusta and Interstate 85 north for Greenville. These connections occur in six miles for Interstate 20 and 19 miles for Interstate 85. Photo taken by Chris Patriarca (02/23/03).
Approaching the gore point for the Interstate 285 east and westbound ramp split. Atlanta Airport is added to the Interstate 285 westbound control point list. Also check out the original Interstate 285 button copy panels and lighting fixtures as they appeared in 1999. Photos taken by Chris Patriarca (02/23/03) and Jim K. Georges (07/99).
The close proximity of Exit 53 of Interstate 285 westbound allows for a U.S. 23 exit ramp from the Interstate 675 northbound ramp. This photograph shows the sign bridge motorists encounter at that location. Photo taken by Chris Patriarca (02/23/03).
In the other direction, this view shows the transition from northbound Interstate 675 to eastbound (northbound) Interstate 285 (outer loop). Photo taken by Alex Nitzman (05/28/05).
Perspective from Interstate 285 west
Interstate 285 westbound, one mile from Exit 51/Bouldercrest Road and two miles from Exit 52/Interstate 675 south. Note the truck restriction in effect for the left two lanes of Interstate 285. Photo taken by Chris Patriarca (02/23/03).
Now one mile within the northern terminus of Interstate 675 at the Exit 51 diamond interchange. The southbound control city of Macon pertains to Interstate 75 and is located 71 miles to the south. Photo taken by Chris Patriarca (02/23/03).
Interstate 285 expands to five lanes with the addition of an exit-only lane for Interstate 675 south/Exit 52. Photo taken by Chris Patriarca (02/23/03).
Interstate 675 southbound branches southward from Interstate 285 westbound. Montgomery emerges as a control city for Interstate 285. The Atlanta Beltway reaches Interstate 75 in six miles and Interstate 85 in nine miles. Photo taken by Chris Patriarca (02/23/03).
Perspective from Interstate 285 east
Eastbound Interstate 285, one mile west of Exit 52 for Interstate 675 southbound. Exit 51 for U.S. 23 is situated only one-quarter mile west of the northern terminus of Interstate 675. Photo taken by Chris Patriarca (02/23/03).
With U.S. 23/Moreland Avenue in the background, Interstate 285 eastbound progresses with four lanes to within one-quarter mile of Interstate 675 southbound. Photo taken by Chris Patriarca (02/23/03).
Interstate 675 southbound begins as Interstate 285 eastbound continues toward Interstate 20 in six miles. The first southbound exit of Interstate 675 (Exit 7) connects with Anvil Block Road just east of U.S. 23 and Fort Gillem. Photo taken by Chris Patriarca (02/23/03).
Interstate 285 northbound at Interstate 675 (same sign bridge Pictured above) during a sign replacement project. Note the old sequential exit number of 38 for Interstate 675 southbound. Vidcap taken by Alex Nitzman (06/05/96).
