FM 1821 begins at an intersection with FM 1195 near Mineral Wells Airport. The highway starts out running in a west direction along MH 379, then turns north onto Garrett Morris Parkway. FM 1821 travels through more rural areas of Mineral Wells before running near a subdivision and retail center near US 180.

As designated on November 20, 1951, FM 1825 originally included only the segment from Three Points Road eastward, which intersected with U.S. Highway 81 (US 81) at the time. On January 18, 1960, the alignment of US 81 was altered to align with I‑35. At this point, FM 1825 was extended south 1.1 miles (1.8 km) to intersect with the new I‑35 alignment, and Three Points Road between FM 1825 and I‑35 was added as an unsigned spur. On June 27, 1995, FM 1825 was redesignated as Urban Road 1825 (UR 1825). As with most other Urban Roads, no signage changes have been made to indicate the new name.

On March 26, 1953, the route number was assigned to the present route in Jeff Davis County, and was to be cancelled and relinquished back to county administration upon completion. Because the route was completed by September 20, 1954, the route was cancelled and relinquished back to county administration that day. On September 20, 1955, the state again assumed control over the road's maintenance, and the road was again designated as FM 1837. The road was given its current ranch to market designation on October 1, 1959.
Farm to Market Road 1837 (FM 1837) was originally designated on November 20, 1951 as a 4.8-mile (7.7 km) road in Kaufman County.

On December 17, 1952 it was extended 10.7 miles (17.2 km) south to SH 48, and the north end became part of FM 732 (which had its east end there). On October 26, 1954, this section of FM 732 became part of FM 510 which had extended west. On June 28, 1963 it was extended another 5.6 miles (9.0 km) northward to FM 2358, with another extension northward to Arroyo Colorado on November 10, 1967, replacing part of FM 2358, which was canceled as the remainder west to FM 803 became part of FM 106 as several farm to market roads in the area were changed. The road at the north end would become part of FM 2925 (which ended there) on November 3, 1972. FM 2925 was extended east from FM 1847 on May 7, 1974, so the roads were no longer end to end.
