Crews are working to repair a water main break near between Northern Blvd. and Cherry Road.
Water is expected to be restored to those in the area in the early morning hours Saturday; those homes may experience low or no water pressure until then.
A Friday Facebook post from the Rio Rancho Police Department advised drivers to avoid the southbound Unser Blvd. from Cherry to Northern.
Free bottled water is available for pickup at Fire Station 2, 1490 Cherry Road, with a three bottler per person limit.
