PR 466 is a north-south provincial road that begins at PR 465 near the unincorporated community of Cordova, and travels to its northbound terminus with the Yellowhead Highway near Franklin.

In the early 1990s, the Manitoba government decommissioned a number of provincial secondary roads and returned the maintenance of these roads back to the rural municipalities.

A large portion of the original PR 466 was included in this decommissioning.

Prior to this, PR 466 continued east in concurrence with the Yellowhead Highway for 1.6 kilometres (0.99 mi) to Franklin Road.

From this point, it travelled north through Franklin and terminated at a junction with PR 471.
