    Wow we need a professor to tell us that fire on metal will make it weaker. What we need is for tanker drivers to slow down on exit ramps that have sharp corners, especially if loaded with fuel.

      Apparently we need both. Even after the prof folks in the comments still don't believe a petro fire has the ability to weaken steel!

    I am a retired FDNY Captain, and the prof is correct. Steel weakens at 1000 degrees and losses 40% of its weight bearing capacity. As temps get higher the steel softens and warps from the weight stresses upon it. (Just like WTC) That section the steel was only carrying its own weight, (steel and slab), yet it collapsed as they always do. (Lookup the many prior highway collapses over the past years). Anytime you have unprotected steel it is at risk from heat -degradation. (Like WTC) These fires are way too common, and show how easy it is to shutdown our road networks. To learn more on WTC see my books,

      Richard, bullshit! As a welder, the steel will only weaken if the heat is directly on it for an extended length of time. This didn't happen in this case.

      @@morales1961 Your wrong, because you are thinking as a welder. Fires are a different animal. That fire burned very hot, 1400+, and was trapped under the concrete which allowed that intense heat to absorb and radiate the length of the steel. Only the beams exposed to the air might have cooled some. We had dozens of fires in Bldgs that the steel only supported the roof, but they still warped and failed from the heat.

      @@lowandslow3939 25 years of firefighting and years of schooling. We had dozens of fires in NYC where the steel failed even though it only supported the normal roof. In this case the steel was covered by the concrete, which trapped the heat making the heat degradation worse. There is a great shot of WTC 2 from the East that captures what Structural Engineers call the moment of failure. You can see the columns bending as their strength weakened to the point of failure. Then gravity takes over.

      I don't think you want to use China's rapid building projects as examples. They are known to have many problems with quality. A similar incident to this occurred a few years ago on incident on I-85 in Atlanta. It was rebuilt in 43 days. That doesn't mean this will only take 43 days but it does suggest that this could be a couple to a few months. Much of that may depend on finding a steel fabricator who can shift their manufacturing around to put this work at the front of the line.

      It crashed there! The driver lost control coming down an exit ramp that has a sharp curve at the end. He will likely going to fast. The truck flipped over, tank ruptured and 8500 gallons of gasoline caught fire. The Federal Highway Administration (so taxpayer dollars) will likely pay for the repairs. The Feds, state and city will then all seek reimbursement from the truck company's insurance provider.

      It's not 100 years old. We didn't being building the Interstate Highway system until the 50s. If you use street view on google maps and go under this bridge you will see that the steel is fairly new and was in very good shape. This bridge was just replaced 10 years ago. 8500 gallons of gasoline burns at temperatures well over what is needed to weaken steel and cause it to collapse. But with hundreds of thousands of steel bridges in the country this occurrence is so rare that we don't protect against it.

      43 days to replace a similar collapse on I-85 in Atlanta a few years ago. Not saying this will be done in 43 days but it certainly won't take 5 years. It's likely a 2-5 month fix depending on whether there is damage to the surrounding abutments that support the beams and how quickly they can jump to the front of the line of a steel fabricator to get the new beams.
