Future Interstate 777 North Carolina

Hamptonville, NC ↔ Winston-Salem, NC•28.30 miles

Interstate 777 is a proposed designation for the freeway along U.S. 421 extending west from I-40 and Salem Parkway in Winston-Salem to I-77 near Hamptonville in North Carolina. Carolina Core officials sought Congressional support in April 2024 for the upgrading this stretch of U.S. 421 to a future Interstate. The designation is meant to prompt economic growth (Skipper, 2024).

Created in 2018, the Carolina Core initiative of the Piedmont Triad Partnership (PTP) is the proponent of the Interstate corridor. PTP is a leadership organization promoting economic growth by coordinating with and advocating to political officials and regional leads in the Triad area. Carolina Core successfully worked with local, state and federal government officials for the designation of U.S. 421 between Greensboro and Sandford as the Future Interstate 685 corridor (Hill, 2024).
