History
In South Carolina, the southern terminus of Interstate 77 near Columbia, South Carolina was originally the interchange with SC 12 (Percival Road) with mile markers signed accordingly. South Carolina ( is a state in the southern region ( Deep South) of the United States of America. Columbia is the state capital and largest city in the US state of South Carolina. In 1986, an interstate spur to be named Interstate 326 between SC 760 (Fort Jackson Boulevard) and Interstate 26 was planned. Interstate 77 through South Carolina begins its journey in Cayce - south-southwest of Columbia - at an expansive interchange with Interstate 26. Interstate 26 (I-26 is a nominally east-west (but physically more north-south main route of the Interstate Highway System in the Southeastern United States. The decision to extend Interstate 77 from SC 12 and SC 760 (five miles between the two roads) was made before I-326 was opened, so the southern portion was never signed as such and the mile markers for Interstate 77 were adjusted accordingly when the extension was opened in 1995. (Prior to this, southbound traffic on I-77 was detoured, by "Temporary I-77" signage, via I-20 and I-26 to bypass Columbia. ) Because of this, SC 12 and Interstate 77 run parallel for a stretch of three miles (5 km) from Exit 15 until Exit 12. This added a northbound exit only at the 13-mile (21 km) point at Decker Boulevard.
The part of Interstate 94 from Detroit northeast to Port Huron, Michigan was originally planned as I-77 in 1957; the current I-77 was I-79.

As of the 2000 census the city had a population of 32338 with a 2006 estimate of 31302 [1] When the current Interstate 79 was added in Pennsylvania, the I-77 designation was moved to its current route, but the I-77 in Michigan also remained in the 1958 numbering plan. Interstate 79 (abbreviated I-79) is an Interstate highway in the eastern United States, designated from Interstate 77 in Charleston West The Commonwealth of Pennsylvania ( often colloquially referred to as PA (its abbreviation by natives and Northeasterners is a state located in the Northeastern [2] It soon became part of I-94.
