Seems that trail segment is fenced in totally as 0f 1/14/2013 with a sign stating the trail will be closed from 11/12 - 5/13. The trail closed signs appear to be fancy shop made versions, not the typical temporary signs with "fill in the blank" from:____ to:____ dates, so apparently this is a big project. It appears from research that some sort of work may be going on to extend the trail from Cabrillo to El Camino and possibly some road work on San Tomas south of El Camino may be going on, but can't find any official notice of what is actually going on.
Also seems that since the trail was actually not closed until mid-January, the project appears to be about 2.5 months behind already, so the 5/13 end date is probably closer to the end of summer. Seems folks are starting to wonder what is going on:
I find nothing on the City of Santa Clara web site about the trail work, nor do I find anything on the vta.org site (regarding any Expressway work). Have also read snippets on-line about some possible box culvert work along San Tomas Aquino Creek between El Camino and Williams and that would be under valley water control, but nothing on their site either.
So if anyone has any information on what is going on, please pass along any pointers.
