ISLE OF PALMS — Mayor Dick Cronin was driving on Palm Boulevard Sunday morning when his car was suddenly jolted.

Cronin said he didn’t know what to think. Then he saw a four-inch drop-off in the pavement.

He called city Administrator Linda Tucker.

“We’ve got a problem,” he told her.

Later in the morning, a crater-like hole appeared near the centerline.

“I didn’t realize how big a problem it was going to be,” he said.

The situation occurrred because AT&T was working on a line and hit a storm drain pipe, said state Department of Transportation spokesman James Law.

“We will be working tonight toward repairing Palm Boulevard and regret causing any inconvenience,” said AT&T spokesman Josh Gelinas.

Traffic continued to flow Monday on steel plates placed as a temporary measure over the affected section of road.

“Hopefully they can fix it in one night but it might take two,” Law said.

There was no structural damage to the road, he said.

Palm Boulevard is a major east-west thoroughfare on the island. The affected section of the road is between 8th and 9th avenues.

“Making sure that it was in safe condition, that was our biggest concern,” Cronin said.
