Does anybody know what they are doing after all this time?
“The California Department of Transportation (Caltrans) announced today that it will tentatively close the Webster Tube from June 17 through July 6, and the Posey Tube from June 30 to August 11, for a construction project that will remove portions of a fiber reinforced concrete overlay from the ceiling.”
I remember when I was a kid growing up in Alameda and the tube was nice and clean green and brightly lit. Now it seems they close it twice as much as they used to and it is dirty, falling apart, dimly lit (some lights not even working), and seems to be constantly under construction. It looks like crap. I have just recently moved back to Alameda. Are my tax dollars being wasted here? What gives?
Those things were built in the 20′s. I white knuckle it through them every day on my way to and from work.
Why was the tube closed this morning at 4:30 12/20/11?
