It was determined by the National Transportation and Safety Board that the bridge has had structural design flaws from the beginning. These flaws, though not sufficient to cause a collapse during regular use, were sufficient to cause a collapse during the bridge's repair when all of the construction equipment and gravel for concrete making was on it in addition to the load of rush hour traffic.
These were the errors noted in their report:
- Insufficient bridge design firm quality control procedures for designing bridges, and insufficient Federal and State procedures for reviewing and approving bridge design plans and calculations.
- Lack of guidance for bridge owners with regard to the placement of construction loads on bridges during repair or maintenance activities.
- Exclusion of gusset plates in bridge load rating guidance.
- Lack of inspection guidance for conditions of gusset plate distortion.
- Inadequate use of technologies for accurately assessing the condition of gusset plates on deck truss bridges.

Why did the I-35 W bridge in Minneapolis collapse?
the i-35W bridge collapsed because there was to much structural stress on the bridge at the time, when the bridge collapsed it was rush hour time so there was to much weight on the bridge. ^^^NO! the bridge collapsed because the design was flawed. the gusset plate that failed was too thin for the loading. this was the engineers error, hence the lawsuit.
How did the tacoma narrow bridge fail and break into pieces?
The original Tacoma Narrows Bridge that was opened in 1940 collapsed due to heavy winds. The roadway twisted and vibrated violently under 40-mile-per-hour (64 km/h) winds on the day of the collapse.
How do bridges stay up?
A bridge has three things to complete the foundation to keep it from collapsing. They are called spread footings, caissons and piles. It also has the deck itself. +++ All these components are also very carefully designed to withstand the various stresses that they will bear in service.
Why are properties of materials important to engineers?
It's very simple: If you use a material with lower strength or hardness, your entire project could collapse on itself. I'm reminded of a US bridge in which a contractor used the wrong metal for metal struts connecting the cement beams. The bridge collapsed, throwing dozens of vehicles into an icy river; many people died. The bridge tore itself apart under tons of weight, simply because the wrong strength of metal was used.

Where is the Mothman in Minnesota?
Mothman is a legendary moth-like creature, who is said to have originated in the West Virginia area.

The creature was allegedly observed earlier in the month prior to the collapse in Stewartville, Minnesota.
