Farm to Market Road 270

FM 270 begins at an intersection with FM 646 (future SH 99) in League City, Galveston County, heading north-northwest on two-lane Egret Bay Boulevard. The road heads past residential areas to the west and fields to the east before passing through more fields and reaching an intersection with SH 96. The highway continues into a mix of residential and commercial areas with some fields and trees. FM 270 becomes a five-lane road with a center left-turn lane and continues through more developed areas, turning northwest and crossing FM 518. The road widens to seven lanes total and passes businesses before heading into wooded areas and crossing the Clear Creek into the Clear Lake City section of Houston in Harris County. FM 270 heads through residential areas before passing commercial establishments and ending at an interchange with NASA Road 1. Past here, the road becomes El Camino Real.[1][2][3]

The original FM 270 was established on June 11, 1945 in Hopkins County as a route from Sulphur Bluff to the village of Dike. It was extended south 4.1 miles to a road intersection on November 23, 1948. On September 28, 1949, it extended south to SH 11. On August 8, 1951, it extended south 5.5 miles to a road intersection, replacing FM 1698. On December 7, 1952, it extended northeastward 5.8 miles from Dike to a road intersection. On August 24, 1955, it extended east and north 8.9 miles to SH 11 in Pickton. On October 31, 1957, it extended north 5.4 miles to FM 71. On October 31, 1958, it extended north 2 miles from FM 71. The route was cancelled on December 21, 1959 and the highway was transferred to FM 69 and FM 269.[1]

The highway was reestablished on October 30, 1970, running from NASA Road 1 to FM 518 and was extended on August 31, 1987 to its current distance.[1] On August 27, 1995, the state of Texas officially canceled the road in favor of an Urban Road designation, but the designation is only used by the state itself.[4] On November 15, 2018, the state of Texas officially canceled the Urban Road designation in favor of the FM 270 designation.[5]
