A number that I saw some 45 years ago that has stuck with me, and I think of somewhat often, is this: 1 inch of rain per hour produces a cubic foot of water per acre per second It does not take very many acres or very many seconds before you are talking about a lot of water. With the...

Since they are apparently not removing the section of track at the column, I now believe that they replaced all of the bolts at both ends of that section. That's the only explanation I can come up with for the work that they did at both joints.

Local media is reporting that the failed column was removed on Wednesday, July 12 and that the new column is to arrive on Thursday, July 13.

Workers are at the upstream side of the track this morning. So all I can guess is they are making sure that the bolts are all removable so that they can remove that section of track when the new column arrives. Removal of grout at the base of the verticl column also continues. Question though...

There are also two workers checking the track joint downstream from the failed column.

Workers are currently removing the grout from the bottom of the angled column, so clearly they are planning to replace both complete columns and nut just the vertical column and the top section of the angled column.

It looks as though they have welded some (hopefully) temporary plates across the crack in the support column.

"I'd like to be remembered as an innovator," Rush told vlogger Alan Estrada in 2021. "I've broken some rules to make this. I think I've broken them with logic and good engineering behind me. The carbon fibre and titanium, there's a rule you don't do that. Well, I did." I am curious to see in...

The camera system being used may be fairly high resolution, but there is a tremendous amount of compression being done to keep the required bandwidth low, so the pictures we are getting are fraught with artifacts.

The first concrete truck has arrived on scene. Edit: Concrete truck was only there a short while, and there was only one of them. Reason unknown.

The I-95 webcam has been relocated to the top side of the bridge, looking south(?), so once again we have a reasonably good view of what they are doing. Thank you PENNDOT. We are now looking in almost the opposite direction. Visible is the north side of the fill. Before we were seeing the...

As Retiredat46 stated above, compaction was limited to two Bobcats and two handheld vibrating compactors. That is the limit of the compaction. Also, the black fabric is some kind of metal mesh, because once in place it was welded to vertical bars (maybe 6 foot in length each). So the fabric...

It is fascinating to watch the construction process. They appear to be using a weldable mesh material, about 10' by 15' or 20' in size to anchor the entire structure together. First a layer of this mesh was laid down, with the end two feet or so bent upwards vertical, but the rest lying flat...

The road going under the bridge makes an abrupt curve to the left just before going under the bridge. My guess is that the gasoline tanker was going too fast for the curve and overturned. But that is just my guess.
