This project involves the improvement of a 63.7 mile segment of U.S. 27 (S.R. 25) between State Road 826 in northwest Dade County, through Broward County to the city of South Bay. Construction of six lanes is proposed for the 4.9 mile segment from S.R. 826 to S.R. 821 (Florida's Turnpike) and widening to four lanes is proposed for the remaining 58.8 mile section to South Bay. Frontage roads are also proposed along major portions of the project where possible future development is anticipated.
