the BNSF Railway bridge on the Spring River, at Mammoth Springs, that was washed out from under the empty coal train cars last week, was rebuilt in under a week! How in the hell the BNSF crew pulled that off? No clue, but damn, lets hear a round of applause for that crew! Amazing!

The reverse of the typical before and after, but, the before photo doesn't do a good job of showing what they did, comparatively, so I'm leading with the after image

The rebuild, which included the construction of a brand new bridge, is the type of project that would normally take months to complete.

Earlier in the week, BNSF predicted it would have the bridge replaced and the line back open by Friday morning. However, after herculean efforts to remove wrecked railcars from the river, install a new span, and replace the track, the project was completed almost 24 hours ahead of estimates.

This week, crews worked day and night, using large machinery to clean up the mess and reopen the line. On Thursday, BNSF issued an advisory to rail customers, letting them know the line was back open at 7:05 a.m. and route was back open.
