Zilwaukee Bridge in Michigan is the perfect example on how not to build a bridge
Located in Zilwaukee, in Saginaw County in the U.S. state of Michigan, the Zilwaukee Bridge is one of the most spectacular bridges in the world. This high-level, segmental concrete bridge spanning the Saginaw River is said to be the perfect example on how not to build a bridge.
The bridge carries the I-75 / US 23 road. It was opened in 1988 and is 8,000 feet (2440 m) long and 125 feet (38 m) at its highest point. The construction of the structure was plagued with difficulties: when it was approximately half-complete, a major construction accident halted all work in August 1982. The accident delayed construction for over 2 years.
