Not sure where I came across this.

That is really interesting how they pre-assembled both approach spans and tipped up into place. I wouldn't have guessed constructing in that manner. Great pic!

To think this work was done under traffic is very interesting too.

That's very true. I have done multiple rail bridge rebuilds, a 260' long tunnel that was 20' dia 70' below the RR grade (creek restoration), all with active rail. I was only dealing with 2 to 3 trains on a normal day but dealing with track warrants, flagged at both ends every time you foul the track, it can be very involved and everything pre-planned around traffic demands and not the construction schedule!
