Message: [QUOTE="sutomcat, post: 3278161, member: 27"] My guess is that there is something wrong with the spirals and/or box girders needed to close the gap between the groupings. That or they just don't have the parts yet. I suspect at least one spiral is out of spec and needs to be replaced (they one they tried a couple of times to put in place). Anyway, I am guessing they are going to skip that part of the crown truss for a while and move on, probably adding on to the crown truss on the western and eastern sides, away from the gap. The parts received today suggest this is the case. Hopefully we see some progress tomorrow. I didn't see spirals or box girders delivered to the east side but maybe they are coming a little later. I could have missed them too. Work makes following this stuff quite inconvenient... [/QUOTE]
