History

Part of FM 812 was once known as the Austin-Port Lavaca Stagecoach Road.^[2]

FM 812 was first designated on August 26, 1948, for the road segment between SH 29 (along the current US 183 alignment) and Elroy. It was gradually extended southeast on SH 21 on October 28, 1953, to 7.0 miles (11.3 km) southeast on May 2, 1962, and to its current terminus near Red Rock on May 6, 1964.

Route description

FM 812 begins at an intersection with FM 20 just west of the community of Red Rock in western Bastrop County. From there, it proceeds northwest, passing through the community of Elroy, and ends at US 183, just south of Austin-Bergstrom International Airport in the community of Pilot Knob.

For a 0.5-mile (0.80 km) segment east of Pilot Knob, FM 812 runs concurrently with FM 973.
