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 (I-8) freeway system.

[1] The two spans rise 450 ft (137.2 m) above the valley floor,[1] 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 (SCR-33) 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".

Greer's design re-routed the freeway to the south through Pine Valley Creek Canyon, bypassing and preserving the quaint beauty of this eastern San Diego County mountain community.
