John Young Parkway is a four- and six-lane surface road from near Campbell, Florida through Kissimmee, Florida to northwestern Orlando, Florida. It serves as an alternate to the parallel Orange Blossom Trail.
The original section of John Young Parkway was built by the Florida Department of Transportation in the early 1970s, from Colonial Drive (SR 50) west of downtown Orlando north to Orange Blossom Trail (US 441 (SR 500)) at Lee Road. It was assigned the number SR 423 and named after John Young, an astronaut from the Orlando area.
Over the years, extensions to the south have been built, some by Orange County and some by the state. Additionally, Osceola County extended it south to meet the existing Bermuda Avenue in Kissimmee.
Around 2000, Bermuda Avenue and Orange Blossom Trail in Kissimmee were renamed to John Young Parkway. Now John Young Parkway ends at the Kissimmee city limits, a bit north of the intersection with Pleasant Hill Road, where the older Orange Blossom Trail name continues.
Traffic volumes along JohnYoungParkway are continuing to increase due to growth within the community.
In addition to the six lane widening of JohnYoungParkway, additional capacity improvements will be made along the corridor.
These include an additional through lane along Americana Boulevard, replacement of the signal and extension of turn lanes for all approaches to the JohnYoung Parkway/Americana Boulevard intersection, extension of the south bound turn lane at Park Central Boulevard, and an extension of the turn lanes for Millenia Boulevard.
