It exists in seven different unconnected segments that total 27.5 miles (44.3 km) in length,[2][3][4][5][6][7][8] acting as connecting roads, neighborhood streets, and arterial routes.

[9][10] After following the canal northwest as a two-laned road for about half a mile, Southwest 87th Avenue turns north and takes on this alignment until the northern reaches of Kendall.

Galloway Road reaches suburbia by Southwest 216th Street, still with the canal beside it as it travels north, passing by schools, gated condominium communities and the backs of residential neighborhoods.

More houses line Galloway Road as it continues north, crossing into the village of Palmetto Bay at Eureka Drive (Southwest 184th Street).

North of here, Galloway Road continues for one block where its southernmost section terminates at a T-intersection, with the bulk of traffic encouraged to turn left and travel westward along Southwest 164th Street.

[2] On the other side of Canal C-100 from the previous T-intersection, Galloway Road/Southwest 87th Avenue resumes at Southwest 163rd Terrace on the same alignment as a two-laned residential road.

To the north of the expressway, Galloway Road forms the boundary between Sunset and Olympia Heights[17] as it passes housing on its right and a string of Miami-Dade County facilities on its left, including a water treatment plant, cemetery and emergency services.

Here, Galloway Road enters Fontainebleau,[14] immediately crosses the Tamiami Canal and continues for another half-mile (0.8 km) past condominiums to intersect Flagler Street and the western terminus of SR 968.

[1][11][15][18] Beyond Northwest 12th Street, Galloway Road crosses a CSX branch railroad line and then travels through a large business precinct punctuated by big-box retail, restaurants and office buildings until it reaches Doral Boulevard, where the CR 973 designation ends.

Here, Galloway Road leaves Doral and enters unincorporated Miami-Dade County with no designated communities,[19] and loses its central divider.

[5] A second section, little more than an industrial laneway, starts across the nearby Florida East Coast Railway tracks and travels north for a few blocks, terminating at the Miami Canal.
