Alternative IV: Most Economically Viable

Alternative IV focuses on creating the most economically viable alternative by combining the goals of Alternatives II and III.  This alternative aims to minimize the environmental impacts and the impacts to the Angeles National Forest while simultaneously minimizing the travel time.  In order to accomplish this, the alignment begins underground at Burbank station and tunnels northwest for approximately 18 miles.  The alignment daylights through Soledad Canyon for a short segment before tunneling through the northern stretch of the San Gabriel Mountains.  The alignment daylights once again in Palmdale and travels in an aerial structure for approximately 3 miles before returning at-grade at the Palmdale station.
