I forgot to add the water in the creek also provides drinking water to Fremont, Union City and Newark. My source indicates that Caltrans wanted to eliminate the curve over the WP tunnel and the bridge just west of that location by re-sculpting the hills and building a smoother viaduct connection through the sharp narrows in the area.
This would impact the water quality and Caltrans could not come up with a resanable mitigation during construction to maintain water quality, they also proposed a 2nd bore along side the RR tunnel, but my understanding was the UP said not on my watch.
This is still working its way through the process with yet another engineering solution being developed. We are now 15 years into the process and not one shovel has turned and not likely to for another 5 to 10 years.
