National Route 3 begins as the Winter Park Expressway heading westbound from a small expressway portion of Takeda Downs Avenue in north Koiwai. It was planned to continue east through the city along the path of what is now Athalon Street, but its route was truncated in the early planning stages of the National Route System. The freeway portion of Takeda Downs Avenue distributes traffic from the expressway onto downtown streets. Approximately three-fourths of a mile west of Takeda Downs Avenue is the Winter Park Toll Plaza, which collects toll for travelers westbound out of the city. The Red and Orange lines of the RTS Koiwai run elevated directly adjacent to the expressway to Winter Park Transit Mall.
