FORT MYERS, Fla.-- A water main break at the intersection of Dunbar St. and Pauldo St. in Fort Myers forced a school bus into a sink hole Friday morning.

Two Lee County students and a bus driver were on the bus at the time. No one was injured.

Crews had to pump hundreds of gallons of water out of the hole in order to spot the problem: a crack about 4 feet long in a cast iron pipe.

It's not known what cause the pipe to burst, but officials with Fort Myers Public Works tell WINK News the cast-iron pipe is fairly old.

Several dozen homes in the area, as many as 80, will be placed under a boil water notice.

Crews expect to have the water line repaired and the road repaved by 5 p.m. Friday afternoon.
