How is the building of I-285 so important to transportation?

is an Interstate Highway loop encircling Atlanta, Georgia, for 63.98 miles (102.97 km).[2] It connects the three major interstate highways to Atlanta: I-20, I-75 and I-85. Colloquially referred to as The Perimeter, it also carries unsigned State Route 407 (SR 407), and is signed as Atlanta Bypass on I-75/I-85.

Because of suburban sprawl, it is estimated that more than two million people use the highway each day, making it the busiest Interstate in the Atlanta metropolitan area, and one of the most heavily traveled roadways in the United States. During rush hour, portions of the highway slow, sometimes to a crawl.
