Since March 16, the last drawbridge on the Overseas Highway has only opened once an hour.
Before that, it opened twice an hour — which caused massive backups through the village of Islamorada in the Upper Keys, said Islamorada Mayor Mike Forster.
On Thursday, the Coast Guard informed the village that it would be extending the test period of once-an-hour openings for another 30 days, Forster said. The test period had been scheduled to end this Tuesday.
"It's been pretty effective," Forster said.
