Loop 494 is a state highway loop in the Greater Houston area of Texas. It is 9.7 miles (15.6 km) in length and is a former routing of US 59 in the area.[1]

Route description

Loop 494 begins at I-69/US 59 just south of the Harris–Montgomery county line.[2] The route travels northward, paralleling the freeway to its west. It passes the community of Kingwood and the unincorporated area of Porter before reaching New Caney, where it has a brief concurrency with FM 1485. Shortly thereafter, it connects once again with I-69/US 59, where the Loop 494 designation ends.[1][3]

History

Loop 494 was designated on October 2, 1970, after US 59 was moved to the extension of the Eastex Freeway into Montgomery County.[1]
