SH 184 begins in the west at its junction with US 491 near Lewis and travels ESE to Mancos.

The highway has a one mile (1.6 km) overlap with SH 145 just south of Dolores which is not technically part of SH 184 making the actual driving distance from Lewis to Mancos just over 26.5 miles (42.6 km).

It also intersects US 160 near Mancos, near its eastern terminus at US 160 Bus.

Most of the route was deleted by 1954, leaving approximately nine miles near Mancos.
