The road is one of the longest farm-to-market roads in the state at almost 95 miles (153 km). It starts at U.S. Highway 90A near downtown Houston and passes south and southwest through Harris, Brazoria, and Matagorda counties.

Inside Houston, the road has been designated as Urban Road 521, but the designation is only used in official state files. In Houston, it's known as Almeda Road. South of South MacGregor Way, Almeda Road has a wide median, and this was the originally proposed alignment for the South Freeway.^[2][3]
