It currently runs for 233 miles (375 km) from South Haven, Kansas at US 81 to Madill, Oklahoma at US-70. It passes through the states of Kansas and Oklahoma. US-177 begins concurrent with State Highway 199 at the US-70 junction near Madill, Oklahoma. From this point, it heads northwest, serving as the southern terminus of State Highway 1 and the main street of Mannsville. The route turns northward in Dickson, where it splits from SH-199. East of Gene Autry, it is the eastern end of SH-53. US-177 then runs through the Chickasaw National Recreation Area and the town of Sulphur, where it has a brief concurrency with SH-7. On the north side of Sulphur lies a partial interchange with the Chickasaw Turnpike.
