The highway was originally created in 1984, but a road extending from Kendall to Sumas has been on maps since 1966 along the Sumas–Glacier route of the Chicago, Milwaukee, St. Paul and Pacific Railroad.

State Route 547 begins at a junction with SR 542 in Kendall, located northwest of Mount Baker.

[1][3] SR 547 turns northwest and passes the former Baker's Edge Golf Course, Peaceful Valley and Columbia before turning west and becoming Reese Hill Road as it traverses the north foothills of Sumas Mountain.

The roadway ends at an intersection with SR 9, about 0.67 miles (1.08 km) south of the Canada–US border.

The road had deteriorated, but the Whatcom County stated they were unable to afford repairs.
