The Florida Keys checkpoints at the county lines on U.S. 1 and Card Sound Road will remain up, Monroe County officials said Sunday. The county, Monroe County Sheriff’s Office and Keys cities “have partnered” to keep the checkpoints going. The county and cities will be supplementing the Sheriff’s Office with police officers, fire rescue, or public works employees, county spokeswoman Kristen Livengood wrote in an email. She said the checkpoints would be up “until further notice with periodic review.” Keys residents, property owners and “those actively involved in work in the Florida Keys” are admitted, including trucks carrying fuel, groceries and other deliveries. An estimated 2,000 people in 788 cars were turned away in the checkpoints’ first 48 hours of operation, according to the Monroe County Sheriff’s Office. Keys residents can show proof of residency can be demonstrated with a resident reentry sticker, or a hard copy of local identification, utility bill, deed, lease or tax bill.
