The construction of I-77 began in the late 1950s, as part of the Federal Aid Highway Act of 1956, which established the Interstate Highway System.

I-77 was officially opened to traffic in 1971, although some sections were completed earlier, such as the segment through Charlotte, North Carolina, which was opened in 1965. The highway has undergone several improvements and upgrades over the years, including the construction of new interchanges and the widening of existing lanes. I-77 has also been the subject of several studies and proposals, including a proposed extension to Myrtle Beach, South Carolina, and a planned upgrade to the highway's intersection with Interstate 81 in Wytheville, Virginia.
