Texas State Highway Loop 335
Loop 335 is a highway loop that encircles the city of Amarillo, Texas, United States. Loop 335 connects to every major highway in the city and passes close to Amarillo International Airport on the east side of the city. Loop 335 is not currently a continuous freeway. Instead, the highway has interchanges at select junctions and short segments of freeway such as its southeastern section. Route descriptionLoop 335 makes a complete loop around the city of Amarillo. The highway passes in and out of the city and, as of January 2024, skirts most development. NamingLoop 335 has several local names:
Lane configurationBecause I-40 runs east–west and I-27/U.S. Route 87 run mostly north–south through Amarillo, Loop 335 can be divided into four sections: northeastern, southeastern, southwestern, and northwestern. The two junctions with I-40, the junction with I-27, and the junction with US 87/US 287 are all grade-separated. Additional grade separations are listed below.
HistoryLoop 335 was designated on January 18, 1960, from US 60 and US 87 south of Amarillo eastward and northward to US 287. On January 31, 1961, Loop 335 was extended northward and westward to US 87 and US 287. On July 30, 1965, Loop 335 was extended westward and northward from US 60 and US 87 to US 66. On June 21, 1977, a section of FM 1719 from Loop 434 to the new location of US 87 and US 287 was transferred to Loop 335. On July 24, 1984, Loop 335 was extended west and south to the point of beginning, completing its current route, and also replacing another section of FM 1719. On April 26, 2018, Loop 335 was rerouted from a point 1⁄2 mile (0.80 km) south of SW 9th Avenue, to Interstate 40, to Helium Road, to Farm to Market Road 2186, and back to existing Loop 335. The old route, a section of Soncy Road, was transferred to FM 2590. However, this will not be effective until construction on this portion is completed.[5][6][7][8] FutureIn 2015, the Texas Department of Transportation (TxDOT) published the plans for the all new Loop 335 freeway that encircles the city of Amarillo.[9] TxDOT has planned multiple multi-level interchanges that junction with Interstate 40, Interstate 27, US 287 and US 87. The first interchange, on the east side of Amarillo, is a multi-level interchange that provides access to both directions of the I-40 freeway and Loop 335. The second interchange with I-40, however, is a full stack interchange.[10] On the northern side of Amarillo, the loop will be completely reconstructed to an Interstate-grade freeway with complete grade separations and will be expanded to 4 lanes. It also includes a stack interchange that will connect the new freeway to the future I-27 Ports to Plains Corridor (US 287, US 87).[11][12] I-27 in southern Amarillo will be entirely reconstructed from the Country Club Road interchange to Palo Duro Canyon State Park. It will accommodate 6 lanes at the mainlane bridge along with a complete stack interchange with direct connectors to and from I-27. Furthermore, another triple-level interchange will be built to accommodate Soncy Road, Helium Road, I-27 and the new loop.[12] Also, another new mainlane bridge that accommodates up to 6 lanes is also in the works for I-40 near Helium Road, providing easier access to the new freeway.[13] Although construction started in 2016, the entire project (which includes converting the entire loop to Interstate specifications) is not expected to be complete until 2024.[14][8] The southwest portion of the new freeway opened in June 2024. The original SL 335 was moved off Soncy Road.[15] Junction listJunctions are listed in CCW order. All interchange exits are unnumbered.
