Farm to Market Road 1485 (FM 1485) is a state-maintained farm-to-market road in the U.S. state of Texas in Montgomery County. Its western terminus is at an intersection with State Highway 105 (SH 105) just 3.5 miles (5.6 km) east of Conroe. It travels southeast, ending at Loop 494, in New Caney. The road begins again approximately 0.1 miles (0.16 km) south of its terminus at Loop 494, heading east until it transitions into FM 2100 in Huffman, Harris County.


On July 22, 1949, the first FM 1485 designation was created. It ran between about 9.3 miles (15.0 km) between SH 105 and FM 2090 in Montgomery County. The highway was extended eastward on August 22, 1951, to US 59 (now cosigned I-69), adding about 8.4 miles (13.5 km) to the length. Another 5.4 miles (8.7 km) was added on September 27, 1951 when FM 1485 was extended to replace FM 1773, moving the eastern terminus to the HarrisMontgomery county line. On June 1, 1965, the road was lengthened once more by adding 1.2 miles (1.9 km) in Harris County.[1]

The Texas Department of Transportation (TxDOT) redescribed the routing of FM 1485 in their Highway Designation File on October 2, 1970. They updated the file to denote the gap in the route of the highway at Loop 494 and to show that it has a total length of approximately 24.1 miles (38.8 km) in the two counties where it is located.[1]
