I-4 and C.R. 532 Improvements

Construction projects near the Interstate 4 (I-4) and County Road (C.R.) 532 interchange are underway. These include projects on I-4 between C.R. 532 and State Road (S.R.) 429. They will improve safety and mobility in the area. These construction projects will be closely coordinated, and for the traveling public it will appear as one project.

Project Descriptions

FPID No. 444187-1

This construction project transformed the I-4 at C.R. 532 interchange into a Diverging Diamond Interchange (DDI), with the new traffic pattern having opened to motorists July 2022. The DDI eliminated left turn phases at traffic signals as well as reduced the number of signal phases from four to two, leading to more efficient traffic movement throughout the DDI. Conflict points were also decreased by more than half. A conflict point is any location in the interchange where vehicles’ paths merge, diverge, or cross. These are the most likely locations for collisions to occur. The Florida Department of Transportation (FDOT) project also improved ramps and added bike lanes and sidewalks along C.R. 532.

Construction began in July 2021 and reached final completion in early 2023.

FPID Nos. 444329-1 and 443958-1

Projects under FPID Nos. 444329-1 and 443958-1 were let together and started in late November 2021. Project No. 444329-1 has added new eastbound and westbound Interstate 4 (I-4) auxiliary lanes, one in each direction, between the ramps of State Road (S.R.) 429 and County Road (C.R.) 532, as well as an auxiliary lane on northbound S.R. 429 between I-4 and Sinclair Road. The auxiliary lane on eastbound I-4 opened spring 2023, while both the auxiliary lane on westbound I-4 and the auxiliary lane on S.R. 429 opened summer 2023. The westbound I-4 exit ramp and the eastbound entrance ramp at the C.R. 532 interchange have been widened to two lanes to increase traffic flow and capacity. The project also milled and resurfaced S.R. 429 between I-4 and Sinclair Road.

Project No. 443958-1 milled and resurfaced eastbound and westbound I-4 from the Polk/Osceola County line to west of S.R. 417.

These projects reached completion in March 2024. This is an FDOT project.
