Pine Valley Creek Bridge

The Pine Valley Creek Bridge, officially named the Nello Irwin Greer Memorial Bridge, is a reinforced concrete box girder bridge in San Diego County, California near the town of Pine Valley. The bridge was built in 1974 as part of the Interstate 8 freeway system. At the time of its construction, it was the first bridge constructed in the United States using the segmental balanced cantilever method. The northern span is 1,691 ft long while the southern span is 1,741 ft long. The two spans rise 450 ft above the valley floor, placing Pine Valley Creek Bridge among the highest bridges in the United States.

Originally known unofficially as the Pine Valley Creek Bridge, a California State Senate concurrent resolution officially named the bridge in honor of the project engineer, Nello Irwin Greer, responsible for designing the section of I-8 known as the "Pine Valley Project".
