Interchange Improvements at Hainlin Mill Road

FPID: 437211-1

Project Details

Florida’s Turnpike Mainline/SR 821 and Surface Street Improvements project includes the design of improvements along Florida’s Turnpike Mainline/SR 821 and surface streets between Hainlin Mill Road/SW 216th Street and SR 5/US 1. The project will increase operational capacity, improve safety, address roadway and structural deficiencies, and enhance overall traffic operations at the interchange between Florida’s Turnpike Mainline/SR 821 and Hainlin Mill Road/SW 216th Street.

Other improvements include additional left turn and thru lanes at the intersections of Hainlin Mill Rd. and Cutler Ridge Blvd., as well as a WB left turn lane extension at the intersection of Eureka Dr. and the Turnpike frontage roads. Additionally, a second NB on-ramp lane between Cutler Ridge Blvd. and Caribbean Blvd. will be provided, and will widen the Turnpike mainline bridge 870397 to accommodate the additional ramp lane.

The project includes new noise walls at six locations – including five noise wall gap closures, and a new noise wall along Florida’s Turnpike that extends approximately 1400 feet between Caribbean Boulevard and US 1.

Two noise wall gap closures at MP 5.8, ITS improvements south of MP 7.0, and bridge improvements to the NB bridge over Tallahassee Road (SW 137^th Avenue) were moved from this project to project 444111-1.
