Service is expected to be restored Tuesday morning after a water main break in El Cajon.

A 12-inch pipe burst under Madison and Mollison avenues Monday night.

Firefighters said the water buckled the road and sidewalk. Crews worked overnight to clear the water and fix the pipe and road, but commuters may still expect delays in the area.

In the meantime, water trucks were on standby for two houses and a clinic that lost water service.
