Georgia State Route 920 (SR 920) is a 17.1-mile (27.5 km) arterial road in the Metro Atlanta area in the state of Georgia. The route number is a temporary designation placed along the route while it is upgraded to be converted to be a future alignment of SR 81. It connects the county seat of Henry County, McDonough, to the seat of Fayette County, Fayetteville via SR 54. It is known locally as Jonesboro Street in the city limits of McDonough, Jonesboro Road in Henry County, and McDonough Road in Clayton and Fayette counties. In honor of the late founder of Chick-fil-A, the majority of the route is signed as the S. Truett Cathy Highway.
