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.

This proposal comprises implementation of a four-lane section of highway for a total distance of approximately 8.8 miles in Okaloosa and Walton Counties. The suggested improvements are aligned along a generally different route than that followed by the existing portion of S.R. 30 (US- 98). No particularly adverse environmental impacts are anticipated relative to implementation of this proposal.
