Pallets along the I-4 corridor, Sanford to Celebration

A road signed the wrong way

I-4 is signed east-west but runs on a diagonal, and through Orlando it turns due north between Michigan Street and Kaley Avenue. It is 132.30 miles long, entirely within Florida. Since 2002 its exit numbers follow the miles, so the numbers on the corridor show distance as well as order.

Stops along the corridor, north to south

What the corridor sheds

• Hospitality supply and food distribution in the south and central stretch.
• Light manufacturing and warehouse distribution toward Sanford and Lake Mary.
• Cargo and 3PL freight where I-4 meets the airport roads.

What the interchange numbers show

Reading exit numbers south to north gives the order of the freight. Exit 60 is SR 429, exit 64 is US 192 at Celebration, exit 65 is Osceola Parkway, exit 72 is the Beachline Expressway, SR 528, and exit 101B in Sanford joins SR 417 and the Wekiva Parkway. Exit 94 at SR 434 in Longwood marks the north end of the 21-mile I-4 Ultimate reconstruction, which began at Kirkman Road, SR 435, exit 75. That is 19 exit numbers between Kirkman Road and SR 434.

What the Ultimate project changed

The 21-mile I-4 Ultimate rebuild, from Kirkman Road to SR 434 in Longwood, cost $2.3 billion. It added 53 bridges, replaced 75 and reconfigured 15 major interchanges. Groundbreaking was on 18 February 2015; the express lanes opened on 26 February 2022 and tolling on the four variable-price lanes began on 3 March 2022, with rates set to hold speeds at 60 miles an hour. For a dock, that is the stretch where trucks get an extra lane option when the main lanes back up.

Who runs the express lanes

A private partner, I-4 Mobility Partners, was chosen to design, build, finance and operate the project for 40 years.

How the road was built

Construction began in 1958 and the first segment, from Plant City to Lakeland, opened in 1959. The whole road was finished in 1965, and in 1971 its western end was cut back to Malfunction Junction in Tampa.

Newer work at both ends

The Wekiva Parkway added 2.63 miles of expressway between Orange Boulevard and the I-4 and SR 417 junction in Sanford, and was completed on 26 January 2024. The exit 70 interchange at Daryl Carter Parkway opened in a partial diverging diamond form on 19 July 2025, and the road gained a lane each way between US 27 and World Drive in April 2025.
