Interchanges and Traffic Management
The road was Exit 116 and is now Mile 269 on I-75. It was Exit 1 and is still Mile 1 on I-575, which originally had no northbound exit to or southbound entrance from Barrett Parkway. Those ramps were not built until the late 1980s or early 1990s, a few years after the mall opened. In August 2007, new ramp meters have been installed by GDOT on both the northbound and southbound entrance ramps, and were activated along with the others on I-575 in 2008, as part of the Georgia Navigator intelligent transportation system.
Cobb DOT also operates a traffic camera at this interchange, at Mall Boulevard to its immediate west, at the southwest corner of the I-75 northbound intersection, and at Barrett Lakes Boulevard. Adverse conditions observed on these cameras are displayed on small variable message signs to drivers coming from the northwest on U.S. 41, or from the southwest on Barrett Parkway, just before Old 41 (which becomes Main Street in Kennesaw and Kennesaw Avenue in Marietta). These are the last intersections before 41 and Barrett meet, allowing drivers to take an alternate route if necessary.
To the east, another camera is located at Piedmont Road and Canton Road, however there are no message signs in this direction. Elsewhere along the road, in either direction, there are no cameras or message signs at all.

Famous quotes containing the words traffic and/or management:
“Too much traffic with a quotation book begets a conviction of ignorance in a sensitive reader. Not only is there a mass of quotable stuff he never quotes, but an even vaster realm of which he has never heard.”
—Robertson Davies (b. 1913)
“This we take it is the grand characteristic of our age. By our skill in Mechanism, it has come to pass, that in the management of external things we excel all other ages; while in whatever respects the pure moral nature, in true dignity of soul and character, we are perhaps inferior to most civilised ages.”
—Thomas Carlyle (1795–1881)
