SOUTH PORTLAND — For a second time this week, a water main broke on Route 1 near Cash Corner, closing one travel lane for commuters on Friday.

The break happened before 5:30 a.m. at 317 Main St., in front of the Dairy Queen at the busy Broadway intersection, just 500 feet from the break that occurred early Wednesday and took nearly two days to repair.

“It appears the water valve used for the shut down yesterday has failed and is the cause of the disruption today. It is being replaced,” said Michelle Clements, spokeswoman for the Portland Water District.

Clements said five to eight customers were without water service – three of them car washes. Commuters were advised to avoid the area. Water service was restored at 4:15 p.m. Friday.

District crews finished fixing the previous break Thursday evening at 380 Main St., in front of the Cash Corner Fire Station at Rumery Road, which is the entrance to the Rigby rail yard and a Hannaford Supermarket distribution center.
