I-55 lies entirely within the city of Memphis, passing through the southern and western parts of the city and providing a bypass of downtown for motorists who do not want to take Interstates I-240 and I-40 through downtown to cross the Mississippi River.
I-255 was the former numbering of I-240 between I-55 and I-40 through Midtown Memphis, Tennessee.
