Why The Mississippi River Bridge Collapsed

The I-35W Mississippi River Bridge collapse, a tragic event in American infrastructure history, occurred on August 1, 2007, in Minneapolis, Minnesota. The bridge, a vital artery connecting the northern and southern parts of the city, failed during evening rush hour, sending vehicles and their occupants plummeting into the river below. Thirteen people lost their lives, with many more injured. The collapse brought attention to the state of aging infrastructure across the United States, prompting discussions on the importance of regular maintenance and investment in updating bridges and roads. Investigations revealed design flaws and structural deficiencies in the bridge, highlighting the need for stringent inspection protocols and infrastructure renewal efforts nationwide. The disaster spurred significant changes in infrastructure policy and funding, emphasizing the imperative of ensuring public safety and the resilience of critical transportation networks.

    Not only did the state have to rapidly replace that bridge, they also had to replace an identical bridge in St. Cloud on MN 23, crossing the Mississippi River. The same undersized gusset plates and corrosion were found. The bridge in St. Cloud is also a major artery for the region. That bridge collapse was tragic, but at least the state didn't let another collapse just over an hour's drive north.

    As a University of Minnesota student, I would bicycle across the bridge before it was opened to work at the Pillsbury R&D lab on University Avenue. In the early 70's I became a journeyman ironworker, Local 512, Mpls.-St. Paul. We once worked welding the deck of the Hennepin Avenue bridge (one of the oldest and main bridges downtown). It was built on giant limestone blocks, about 14' cubes. The top was all shale broken pieces. Guy pushed a rebar down into the shale and the 8' rod totally sank !! Called city engineers and bridge was IMMEDIATELY shut down, about 3 PM on a summer Friday.

    Just to be clear… the weight of the construction materials 578,000 lbs that was spread over the bridge is only the equivalent of just over 7 standard loaded semi trucks! US highway standards allow each truck to weigh 80,000 lbs. Only half the lanes on the bridge were open so this load was taking the place of what could have been 4 lanes full of traffic which could have easily included 8 or more trucks which would have been much greater. Additionally, Metro buses could weight up to 48,000 lbs loaded. The bridge actually had less weight on it than it usually carried and most of the construction load was dead load as opposed to truck traffic which would have been a live load. The only reason this diversionary cause persists is to deflect from putting 100% of the blame where it belongs - squarely on MNDoT and the MN state bureaucrats who repeatedly ignored the safety reports and state and local politicians who delayed funding a replacement in favor of new Light Rail construction.

    I've always been afraid of crossing bridges, but people keep trying to convince me that they won't collapse because they're built with redundancy. Apparently, not so. If that bridge in Baltimore is anything to go by, building bridges with redundancy is not the norm. Or at least, it wasn't when most of our bridges were built.

    Not an Engineer here even if I was a Combat Engineer once Upon a Time. I was just one of the guys building and doing rehabs on bridges for a living. Seemed most of the bridges suffered from one particular problem. Lack of proper drainage. After they are built that isn't maintained. Scuppers and piping plugged forever, expansion joints draining on top of what they shouldn't be. The freeze thaw wrecked havoc in those areas. Steel would rust, concrete erode you know all about it. Some designs drain them differently these days. Don't have wide open expansion joints draining on the piers either.

    Reminds me of the Skyway collapsing back in the 1990's. Except that was caused by a perfect storm of conditions, it was a particularly foggy morning, a cargo ship had very poor visibility and thus collided with one of the bridge's supports columns, which subsequently caused the bridge to collapse... The current Skyway was built with this hazard in mind.

    I'm from Ohio, but was living in south Florida at the time and had worked on a nearby hotel a few years before the collapse. Someone ignored the inspection reports showing how the concrete deck and columns had water saturation from the planters, which caused rusty rebar. Unfortunately negligence seems to be a common theme when a structure fails. Why even do inspections if they're just going to be dismissed?

When I left the office and crossed over 35W, I noticed there were no cars heading North, and only saw emergency vehicles heading toward the bridge. I turned on the radio and heard what happened. Amazing that there wasn’t more injuries given how many cars go over that bridge during rush hour.

    The following inspection of all bridges found that sea creatures that once threatened wooden ships adapted to fresh water and were eating the pylons. The bridge was deemed to be in eminent threat of collapse. Being a primary route to 95 north of NYC, the death toll and resulting repercussions of the loss of that route would be catastrophic. The new bridge took about 5 years from start to open. But, then it is over 3 miles long and like 4 times as high as the 35W bridge.
