SR 704 heads east through the suburban West Palm Beach area known as Century Village passing by strip malls and gated communities.

At this point, Okeechobee Boulevard becomes a stroad,[3] commercial and development becomes denser, and the West Palm Beach skyline becomes visible.

East of Congress Avenue, which provides access to Palm Beach International Airport, SR 704 heads towards an interchange with Interstate 95 (I-95 and SR 9), crossing over it, and immediately crosses Clear Lake, with a diamond interchange with Australian Avenue at the eastern end of the lake.

One block east of the interchange, SR 704 crosses railroad tracks owned by Tri-Rail (formerly the CSX Miami Subdivision), and becomes a one-way pair, as it travels along the southern end of downtown West Palm Beach, passing by CityPlace to the north and the Palm Beach County Convention Center to the south.

North of its interchange with SR 704, Australian Avenue continues along the eastern shores of Clear Lake and Lake Mangonia, then northward as a surface road, passing through Mangonia Park before reaching its northern terminus, an intersection with Blue Heron Boulevard (SR 708) in Rivera Beach.
