Route description
SH 186 begins in the Hidalgo County community of Linn at an intersection with US 281 (Future I-69C); the roadway to the west of this junction is designated FM 1017. The route travels to the southeast, passing a section of the Lower Rio Grande Valley National Wildlife Refuge, before turning to a more easterly path and crossing into Willacy County.
