Talk:Caldecott Tunnel

Error on Official Website
The official website refers to State Highway 75 in the 1950s. This is flatly wrong. I have a standard oil roadmap from 1938, and the highway was already shown as 24, not 75. There may have been a 75 earlier than that, but certainly not in the 1950s. Tmangray (talk) 17:27, 26 June 2012 (UTC)
 * There is actualy proof that you are indeed correct:
 * http://teczno.com/old-oakland/
 * The 1950s map calls it 24, and the 1936 map has it stamped 24. 142.254.26.9 (talk) 08:09, 17 July 2021 (UTC)
 * Updating my original comment---the designation "75" was the legislative route number, but 24 was the signed route number.Tmangray (talk) 01:52, 8 March 2023 (UTC)

Hayward Fault
There is no mention of the fact that the Hayward Fault cuts across all 4 bores of the tunnel. What measures, if any, have been taken to deal with earthquakes? Reify-tech (talk) 04:54, 25 January 2014 (UTC)


 * The Hayward Fault doesn't cut thru any of the bores. It's located just west of the western portals.    It does however cut through BART's Berkeley Hills Tunnel which starts further west than the Caldecott. Tmangray (talk) 03:00, 26 November 2016 (UTC)


 * Thank you for the correction, with a reference. I have updated the article accordingly. Reify-tech (talk) 15:37, 26 November 2016 (UTC)

Fourth Bore Description is incorrect
Description of fourth bore is incorrect in that number of lanes should be two, not one and width of the shoulder appears incorrect. Verify from the picture in reference 11 Peter Vander Sar Sept 16 2015≈≈≈≈ — Preceding unsigned comment added by 209.52.88.182 (talk) 07:13, 17 November 2015 (UTC)

The so-called "Kennedy Tunnel"
There is to my knowledge no contemporary mention of the old tunnel's name having been "Kennedy". This appears to be a very recent misnomer which is constantly repeated, without any primary source citation. In all accounts from the opening of the old tunnel and in stories about its various mishaps, and on all official road maps, there is never any mention of the name "Kennedy". The only contemporary mention of Mr. Kennedy was in the SF Call article about the opening of the tunnel in which it says that he was a local who had attempted to construct a tunnel some 25 years before, but failed. The old tunnel was actually dedicated ONLY as the "Inter County Tunnel", as given on the original dedication plaque, and as reported by The Call and other newspapers. I hesitate to make any appropriate changes to the article without some further discussion of this given how often this misnomer has been repeated (it's even the name of an article in the local Wiki for Oakland---I'd discuss it there, but I can't find any discussion page). Unless someone can come up with a reliable, definitive source for "Kennedy Tunnel", I think the changes must be made. Tmangray (talk) 02:09, 8 March 2023 (UTC)
 * Addendum - Footnote 5 cites a short article in the Bay Citizen, but it's rife with error and is too recent. For one, it says the Caldecott opened in 1937 with 3 bores.  It actually opened with 2 bores.  The 3rd opened in 1964.  It also says the tunnel was known as the Kennedy Tunnel and the Broadway Tunnel.  The latter is patently false, and the other is stated with no contemporaneous support as indicated in my original posting above.Tmangray (talk) 23:20, 28 April 2023 (UTC)
 * I've just made what I believe are appropriate and accurate edits according to the evidence available. The confusion between the early failed effort known as the "Kennedy Tunnel" and the later successful "Inter County Tunnel" project has been addressed.Tmangray (talk) 20:25, 3 May 2023 (UTC)
