Fun Fact

The I-35W Bridge’s Engineering

Despite being constructed in the late 1960s, the I-35W bridge had unique engineering elements for its time. It utilized a design known as a cantilever system, which was intended to distribute the weight of vehicles evenly. Sadly, this design also contributed to its vulnerability as issues remained unaddressed over the years.
