The California High Speed Rail Authority have recently posted aerial shots of the various construction sites that are well underway in the California Central Valley, primarily around Fresno. They tend to post updates on their official Flickr account once or twice a month, but most are taken at ground level. Since the Google Earth satellite images are unfortunately over 2-year old at this point, these new photos, taken last week, provide a unique vantage point. Seeing the action from above, you can really understand the scale of the various bridges, and make sense of how they fit in.
The Cedar Viaduct is probably the most important construction area right now because of the impact it will have. The bridge will take trains over CA-99, which sees around 95,000 vehicles passing by every day. Many people are still unaware that HSR is actually happening, so seeing the bridge take shape will have a large impact.

In downtown Fresno, they’re finally finishing the new Toulumne Street bridge. This bridge will carry cars, bicycles and pedestrians over the right of way. The Stanislaus Street bridge, seen above it, will be demolished because it is not tall enough.
A bit north, they’re tunneling under CA-180 to let the trains go through. The trains will go under the highway, under the freight line, and under the canal.
They’ve also rebuilt CA-99 to create a new right-of-way for the rail line.
Another hugely impact project, in terms of visibility, will be where the rail line crosses over the Union Pacific tracks and then over the San Joaquin River – all right next to busy CA-99. This will be extremely visible to passing motorists.
The wet winter means the bridge over the river has been stalled since December.
Rural drivers will go over the rail line in a new overpass, in Madera.
A bridge almost done over a creek.
And the very first active construction site, a bridge over the Fresno River, is wrapping up.
Wrapping up? Yes, the first construction package was for the heavy stuff in the Fresno area – bridges, tunnels, and viaducts. The train stuff – tracks and wires – are part of another construction package that hasn’t been handed out. The idea is to have the full right of way cleared, prepped, and ready to go, and then the last crew comes in and places the rail quickly and uniformly.
Once again, check out the photos in the official Flickr account and keep them bookmarked because new photos get uploaded at least every month, and usually more frequently.
