Bridges are of somewhat greater interest to me right now because they are replacing a major highway bridge right next to my kids' school.
For about 4 months now, they've been building a new "U-Turn section" on the north edge of the existing bridge. It is expected to be complete in the next week, at which point all westbound traffic will be routed up and over the new section and eastbound traffic will be eliminated for (they say) 10 months while the main bridge is demolished and rebuilt. All the parents are a little miffed about the pickup/dropoff traffic being so dramatically affected for so long, but realistically we're the reason the bridge has to be widened in the first place.
The U-Turn bridge was poured into forms; I guess we'll find out if the main bridge is done the same way or partially pre-fabricated elsewhere.
