Construction of I-4 began in 1959. The majority of the interstate was completed by the mid to late 1960s. It was during this time that Mr. Walt Disney made his famous flyover over Orlando. When he spotted the construction of I-4, he selected the future location of Walt Disney World.

Another project, titled I-4 Ultimate, is an overhaul of I-4. It began in 2015 and is scheduled to be completed in late 2020 or early 2021.
