State Road 969 begins at Flagler Street (SR 968) and heads north through residential areas, quickly intersecting the Dolphin Expressway.

Just south of the southern terminus, SR 969 passes through a rail yard operated and maintained by Miami-Dade Transit.

Milam Dairy Road received its current SR 969 designation in 1983, when FDOT reassigned numbers to a collection of southeastern Florida streets.

In the late 1980s, a curve around the airport was extended southward with a bridge over the Dolphin Expressway, removing the portion of North 12th Street from the route.

This curve was implemented after the airport runway was extended during the early 1980s, and the bridge was removed during the post-2011 expansion of the Dolphin Expressway.
