Pine Valley Creek Bridge

The Pine Valley Creek Bridge is a highway bridge in California that crosses a deep canyon using concrete beam construction. The main span extends roughly 450 feet, while the overall height of the structure reaches approximately 440 feet.

The bridge opened in 1974 as the first United States structure built using the cast-in-place segmental balanced cantilever method for concrete construction. This innovative technique marked a turning point in bridge engineering and influenced future projects.

The bridge honors transportation engineer Nello Irwin Greer through its official name, a tribute granted by the California State Senate. This naming reflects the region's recognition of the people who shaped modern infrastructure.

The bridge carries Interstate 8 traffic and sits about 60 miles east of San Diego in California's desert region. It is a major traffic route, so travelers should expect regular vehicle flow when crossing.

Engineer Man-Chung Tang designed this structure entirely from scratch, developing revolutionary construction techniques in the process. These innovations quickly spread and shaped bridge projects throughout North America for decades to come.
