[3][4][5] Southwest 104th Street begins at a cul-de-sac west of The Hammocks, near the Aerojet canal, and proceeds east as a paved two-laned road, providing access to some small farms.

[2] According to the Florida Department of Transportation, State Road 990 begins about 60 feet (18 m) to the west of the southbound onramp to the Don Shula Expressway.

[4] It proceeds through a residential neighborhood for approximately 0.6 miles (0.97 km) before turning back to the east and gaining the Southwest 112th Street designation.

Continuing for another 0.7 miles (1.1 km) past more houses and schools, SR 990 crosses the South Miami-Dade Busway and immediately intersects with US 1, which is the border between Kendall and Pinecrest,[8] and the eastern terminus of the State Road and the historical highway.

[1][4][2][9] Killian Drive/Southwest 112th Avenue continues east of SR 990's terminus through the village of Pinecrest,[8] regaining an urban character as it passes by more houses, although remaining tree-lined and soft-shouldered.

After crossing a couple of canals, Killian Drive meets Ludlam Road (Southwest 67th Avenue) about 1.3 miles (2.1 km) east of US 1.
