This is the second break in a week in the same area.
It happened near Herndon and Polk just after 10 p.m. on Sunday night.
Workers tell us the break is on Polk Avenue between Herndon and southbound Palo Alto.
Water could be seen in one area bubbling up to the surface.
No word on whether the break is affecting homes in the area, or if homes are still getting water from a different part of Fresno's pipeline.
Cars are surrounded by water in the area.
Another happened about a mile away on Herndon and Riverside last Monday morning.
No word on when the current break on Palo Alto near Herndon will be fixed.
