A longer stretch will be reduced to two lanes from 9AM to 9PM Apr. 15-Apr 19 2019.
I highly encourage anyone who thinks that the CALTAIN 2040 plan to expand to four tracks from Mountain View to CA Avenue, to try to drive on Alma Street next week, especially at 5PM. That is what it will be like when half of Alma is closed in order to build four tracks. Although Caltrain has not announced the need to close 2-3 lanes of Alma in order to add the passing tracks, this was included on the last Environmental Impact Statement when HSR proposed the same thing. Caltrain does not have a 100 foot right of way over portions of the track from Mountain View to Palo Alto. 100 feet is necessary for four tracks.
Please contact the Palo Alto City Council if you do not support closing 2-3 lanes of Alma Street.
I am impressed with the newest Palo Alto beta website showing upcoming road closures. However, I could only find it because I have subscribed to weekly updates from the City of Palo Alto on construction and road closures. When I went to the city website, I could not find any link to this site. I'm sure it's there somewhere, but a search for Alma Street construction only linked to articles from prior years - nothing current. There was also no link on the planning site. This may be because the construction is due to PG&E upgrading/replacing the gas line (which I'm glad they are doing), not by the City. Still the beta website is great - I just wish it were easier to find.
