Florida Department of Transportation (FDOT) is working on plans to replace the Howard Franklin Bridge. The project is now expected to cost US$814 million, an increase from the $750 million originally envisaged. The contract is expected to be awarded in 2019, with construction commencing in 2020. The first stage of the project should be ready for use in 2024, providing a significant increase in daily capacity and boosting the emergency evacuation capacity also.
