- Die Pine Valley Creek Bridge, offiziell Nello Irwin Greer Memorial Bridge genannt, ist eine Autobahnbrücke, die den hier Kumeyaay Highway genannten Interstate-8-Abschnitt bei Pine Valley über den Pine Valley Creek führt. Pine Valley ist eine unincorporated community oder census-designated place in den Cuyamaca Mountains im südöstlichen San Diego County in Kalifornien, USA. Die Brücke wurde nach Nello Irwin Greer benannt, dem für die Planung des örtlichen Abschnitts der Interstate 8 zuständigen Projektingenieurs, der dafür sorgte, dass die Autobahn in einigem Abstand von dem Ort mit seinen seltenen Jeffrey-Kiefern gebaut wurde. Die zwischen 1973 und 1975 errichtete Brücke war die erste im Freivorbau errichtete Spannbetonbrücke in den USA und ist dort auch heute noch eine der höchsten Brücken. (de)
- 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. 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 (515.4 m) long while the southern span is 1,741 ft (530.7 m) long. The two spans rise 450 ft (137.2 m) 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 (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". In the original design, the freeway's routing followed the old U.S. Route 80 (US 80) path through the center of the town of Pine Valley. This would have destroyed much of the town and many of the native pines found there. 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. This new design also saved 2 miles (3.2 km) of freeway construction, saving millions of dollars in costs. (en)
