freeway and expressway between State Route 14, the Antelope Valley Freeway, in Palmdale and Interstate 15, the Mojave Freeway, near Victorville. It would also carry a high-speed rail line to Las Vegas, Nevada. Caltrans put the freeway on hold in 2019. State Route 48 is a completely unconstructed 25.5-mile (41.03 km) freeway to connect at the current SR 14/138 junction and West Avenue E, go east running parallel with East Avenue E and East Avenue G, and terminate in Hi Vista at East Avenue G/200th Street East, at the planned SR 122 freeway. State Route 122 is a completely unconstructed 61.3-mile (98.7 km) freeway, defined to run from SR 14 south of Palmdale, and proceed northeast through Hi Vista, and terminate at the current U.S. 395/SR 58 at Kramer Junction. State Route 249 is a 13.5-mile (21.7 km) unconstructed route that would connect SR 2 north of La Cañada Flintridge with SR 14 south of Palmdale. Angeles Forest Highway (CR N3) follows the general alignment, but Caltrans has no plans to take it over. However, there are plans to explore the building of this route between Palmdale and Los Angeles by tunneling through the mountains. A toll road that would run from SR 126 to SR 118 in Simi Valley through the Santa Susana Mountains (proposed in August 1990). The only north–south highways that connect SR 126 with SR 118 are I-5 and SR 23. Motorists on SR 126 can use this route to reach Simi Valley without having to use Interstate 5 via Newhall Pass to SR 118 or SR 23 to Moorpark and vice versa. A good traversable route would be Tapo Canyon Road, Windmill Canyon Road, and Pico Canyon Road, but Caltrans has no plans to take it over.
