CHSRA Releases New Animations of Palmdale-Burbank Routes
The California High Speed Rail Authority has published several new animations of the alternatives for the Palmdale to Burbank segment of the project. These include routes on the Highway 14 corridor and the various proposals to tunnel under the San Gabriel Mountains. Each is embedded below.
First up, the Highway 14 alignment, which is the default option:
Next is the first of the “East Corridor” routes, E1. This is actually the furthest west of the three East Corridor routes, and involves a tunnel that branches off the San Fernando Road corridor near Whiteman Airport and goes under Pacoima as well as the mountains, emerging along the Metrolink tracks near Soledad Canyon:
Then there’s E2, which involves a tunnel under the Burbank Airport, emerging as a bridge across the Tujunga Wash, and then going into a tunnel again until Soledad Canyon:
And finally we have E3, which is a tunnel all the way from Burbank Airport to the Antelope Valley floor just north of the Vincent Grade. This is the furthest east of the corridors, tunneling under Sunland:
Each animation starts in Burbank and flies north to Palmdale, and then turns around and heads south over the route back to Burbank.
At first glance, I’m intrigued to see how much tunneling is involved in the various East Corridor options. And that’s one sharp right turn in E3 coming north out of Burbank.
It’s worth noting that the Highway 14 option also has its fair share of tunneling. If money was no object, one of the East Corridor routes might be worth considering. And if a Highway 14 route is chosen, there should be serious discussions about building a Santa Clarita HSR station at some point.
