Read in the PD article the other day that they hope to lower the new Haystack Landing bridge on Monday, Aug. 17. If it does happen, does anyone know what time it might be?
I'm guessing they will install the tracks, walkways (and the famous SMART bike path?) with the bridge in the lowered position and that's going to shut down NWP traffic on the ROW for a bit.
Oh, yea. I sure did! I sent you a thank you post, but I guess it ended up who knows where. The "Gaslight" is very clearly sitting in the mud on the left side of the picture. You can see her bow and bowsprit there. She's listing to port a bit and probably full of water and in the mud. I don't know if anybody ever hauled her out of there or just left her to sink in the mud and decay to nothing visible, which was pretty much the way they did it those days. I'm sure she'd been stripped of anything useful at that point. They'd just run them up a creek someplace and abandon them back in the day. If somebody took a few core samples in that area, I wouldn't be a bit surprised if they brought up some wood in the core still.
Yes, Karl and his buddy, Roger Olmstead, were scow schooner buffs back when. They rescued Alma, now at the Hyde Street Pier, from the mud flats in Alviso. Roger was the real authority on them. He wrote his masters thesis on scow schooners (for the University of Nevada, of all places! No water there.) Years later, after his death, his widow, Nancy Olmstead, edited and published his thesis, "Scow Schooners of San Francisco Bay," which is the book to which you're referring. (I'm sure because its the only book ever written on them... LOL) I worked with Nancy on that project and IIRC, she gave me a credit the acknowledgements section. Good book.
Duh! Of course, I forgot they have to close the old bridge to get the new one down. They will, still, have to cause some down time on the line because the new bridge requires a realignment of the ROW, though. I don't know what it will take them to accomplish that. They may have to go back quite a ways on either side of the river to achieve a fair approach and avoid a "kink" in the line.
18 day window to move the ROW
I expect they'll adjust for that when they lay the track, although they can do some pretty amazing things with the surveying technology they have these days. The even bigger question is, "What do they do if there's an earthquake and one side moves just a little bit one way and the other side moves just a little bit the other way? !!! Probably no big deal. The D Street bridge in Petaluma is similar, although smaller in scale, and it's been working for God only knows how long.
Maybe I ought to go to work as a fortune teller! I just heard on the news this morning that BART was shut down in order to check track alignment following a 4.0 earthquake in the East Bay. I swear I had no inside information of that earthquake!
I read someplace that they built it "from the ground up." They put all the heavy stuff in first, the ballast, the machinery, and so on, and then built the span up on top of that. I expect they will just start it and lower it on its own power. It was already built and assembled and running for some time (twenty or thirty years... reports seem to differ on age) in Galveston TX. All they did was take it apart like an Erector Set, ship it here, paint it over on Mare Island and then reassemble it here. It ought to work just as well, if not better, than it was working in Galveston. It was a pretty amazing coup by Farhad Mansourian, who scored the bridge as scrap from Galveston for only $4 million I heard. SMART saved about $10 million on the deal, I read somewhere.
Any new forecast on the lowing of the "new" bridge? Looks like the PD got it way wrong.
