Farm to Market Road 521 is a state highway the U.S. state of Texas.
The road is one of the longest farm-to-market roads in the state at almost 95 miles (153 km). It starts near 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.
In the future, the wide median of Almeda Road is the proposed location for the exit lanes of the South Freeway future toll lanes. The exit lanes will travel north on Almeda road and cross over Holly Hall Street before merging with traffic on Almeda Road.
FM 521 was originally designated from SH 36 in Brazoria to SH 35 in Bailey's Prairie. In 1953, the section of FM 524 from its junction with FM 521 to SH 35, FM 1090 from FM 524 to FM 457, and FM 1469 from FM 457 to SH 60 were all cancelled and combined with FM 521. In 1954, FM 1096 from SH 60 west 2.5 miles and FM 460 from SH 35 east 6 miles were cancelled and combined with FM 521. Additional mileage was added from the end of FM 1096 to the end of FM 460. One month later, FM 521 extended northeast 10.8 miles to SH 288 (now BS 288-B). In 1955, FM 521 was rerouted around Wadsworth. Part of the old route was renumbered as FM 2078. In 1956, one section in Brazoria was transferred to SH 332. In 1982, FM 521 extended 30 miles over the old location of SH 288 to US 90 Alternate. In 1995, the section from FM 2234 to US 90A became an urban road, but that designation is only used by the state itself.
From Alternate 90 in Houston to Farm to Market 1462 in Rosharon, FM 521 is signed North/South. From that intersection to the end of FM 521 in Palacios, the road is marked East/West.
Brazos River Bridge
FM 521 runs concurrently with State Highway 332 over the Brazos River bridge into Brazoria in Brazoria County. A new span was built and was opened to traffic in October of 2011, replacing the old bridge, which had been used since the 1930s.
South Texas Project
FM 521 makes a half-loop around the South Texas Project nuclear plant, west of Wadsworth in Matagorda County. Parking along the highway is not allowed on a four mile (6 km) stretch from the west to the east sides of the plant.
