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.

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 also been widened to two lanes to increase traffic flow and capacity. The project will mill and resurface S.R. 429 between I-4 and Sinclair Road.
Project No. 443958-1 is milling and resurfacing eastbound and westbound I-4 from the Polk/Osceola County line to west of S.R. 417.
Construction is anticipated to reach completion in early 2024. This is an FDOT project.

Construction Progress Continues on Interstate 4 in Osceola County
The Florida Department of Transportation (FDOT) continues to add capacity to Interstate 4 (I-4) in Osceola County.
The latest step by the Department to improve mobility along the vital Central Florida corridor is the new auxiliary lane on westbound I-4 between State Road (S.R.) 429 and County Road (C.R.) 532, which opened late last month.
Another new auxiliary lane on S.R. 429 between I-4 and Sinclair Road also opened recently as part of the project, and an auxiliary lane on eastbound I-4 between the ramps of C.R. 532 and S.R. 429 opened in May.
An auxiliary lane is an extra lane connecting the entrance and exit ramps of two consecutive interchanges. The additional lane allows drivers wanting to merge onto the interstate a longer distance to do so and helps reduce bottlenecks caused by drivers attempting to enter or exit the interstate.
Over the past several years, Central Florida has attracted residents and visitors in unprecedented numbers, which has led to increased demand on state roadways. The recently opened I-4 auxiliary lane was constructed to help ease congestion that occurs as motorists merge onto westbound I-4 from S.R. 429 and exit I-4 onto C.R. 532. This new auxiliary lane gives motorists traveling on I-4 from S.R. 429 to C.R. 532 an extra lane, so they do not have to merge into the general use lanes of I-4. The combination of these improvements was designed to increase capacity and improve traffic flow in the ChampionsGate area.
Another major achievement of the project has been the successful installation of guardrail along a 1.1-mile stretch of westbound I-4, separating the I-4 general use lanes from the parallel collector-distributor (C-D) road from S.R. 417. This guardrail, completed earlier last month, was installed to improve safety by discouraging drivers from making dangerous and illegal maneuvers over the grass median in an attempt to cut across traffic.
Additional work includes milling and resurfacing eastbound and westbound I-4 from the Polk/Osceola County line to west of S.R. 417, and milling and resurfacing S.R. 429 between I-4 and Sinclair Road. Milling and resurfacing will create a smoother roadway for motorists and extend the life of the pavement. Construction began in late November 2021 and is anticipated to reach completion in early 2024.
