of Los Angeles. Between the constructed end and legislative end of SR 14 are the community of Reseda and Topanga State Park. There is no paved road that directly connects these two points, with SR 27 or I-405 being the nearest through roads in this area. The interchange with Sierra Highway at Via Princessa in Santa Clarita has an unusual design, with long flyover ramps for the connections. This is the result of a freeway revolt by the residents of Santa Clarita that canceled plans for a freeway extension of SR 126. While the Via Princessa alignment of SR 126 was canceled, the city of Santa Clarita constructed the Cross Valley Connector (CVC) to connect SR 126 directly to SR 14 via Newhall Ranch Road and Golden Valley Road. The final CVC section, the bridge over the Santa Clara River, was opened on March 27, 2010. Future Rapid exurban growth in Santa Clarita, Lancaster, and Palmdale has made the Antelope Valley Freeway one of the most congested in southern California, with average rush hour speeds well below . Future predictions call for continued growth along the SR 14 corridor, including predictions of a tripling of the population of Palmdale by 2030. In response, multiple government agencies have proposed adding more transportation arteries between Los Angeles and the Antelope Valley, as well as expanding the capacity of the existing SR 14 and rail corridors. Several proposals have been made to bypass the Antelope Valley Freeway by boring a tunnel under the San Gabriel Mountains and extending the Glendale Freeway through it to the Antelope Valley. In 2003, Caltrans published a map showing potential improvements to the transportation infrastructure of southern California. The proposal showed both the unconstructed portion of SR 14 and new routes over or under the mountains to Antelope Valley. In 2005, the idea was advanced as a combination toll tunnel and surface highway. Preliminary studies estimated costs around $3 billion and suggested charging a varying toll, adjusted for the time of day, averaging around $8 for one-way passage.
