History of Pittsburgh Bridges

The history of bridges in Pittsburgh dates back to the early 19th century when the city began to expand rapidly due to industrialization. The first significant bridge was the Monongahela Bridge, completed in 1852, which linked the city to the South Side. This marked the beginning of a bridge-building boom that would continue for over a century.

Throughout the late 19th and early 20th centuries, Pittsburgh became a center for steel production, leading to the construction of numerous steel bridges. The city's unique geography, with its hills and rivers, necessitated innovative engineering solutions, resulting in a diverse array of bridge designs.

Key Milestones in Bridge Construction
