The Pine Valley Creek Bridge, also known as Nello Irwin Greer Memorial Bridge, is a reinforced concrete box girder bridge in San Diego County, California, 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 bridge rises 450 feet (140 m) above the valley floor, and is over 1,700 feet (520 m) long.
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 Interstate 8 known as the "Pine Valley Project".
In the original design, the freeway's routing followed the old US Highway 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, bypassing and preserving the quaint beauty of this eastern San Diego County mountain community. This new design also saved two miles (3 km) of freeway construction, saving millions of dollars in costs. However this re-routing of the freeway mandated the crossing of the Pine Valley Creek Canyon. The bridge that now bears Greer's name was the design answer to that engineering hurdle.
Famous quotes containing the words pine, valley, creek and/or bridge:
“Before I finally went into winter quarters in November, I used to resort to the north- east side of Walden, which the sun, reflected from the pitch pine woods and the stony shore, made the fireside of the pond; it is so much pleasanter and wholesomer to be warmed by the sun while you can be, than by an artificial fire. I thus warmed myself by the still glowing embers which the summer, like a departed hunter, had left.”
—Henry David Thoreau (1817–1862)
“Yea, though I walk through the valley of the shadow of death, I will fear no evil: for thou art with me; thy rod and thy staff they comfort me.”
—Bible: Hebrew Psalms, 23:4.
“It might be seen by what tenure men held the earth. The smallest stream is mediterranean sea, a smaller ocean creek within the land, where men may steer by their farm bounds and cottage lights. For my own part, but for the geographers, I should hardly have known how large a portion of our globe is water, my life has chiefly passed within so deep a cove. Yet I have sometimes ventured as far as to the mouth of my Snug Harbor.”
—Henry David Thoreau (1817–1862)
“London Bridge is broken down,
Dance o’er my lady lee,
London Bridge is broken down,
With a gay lady.
How shall we build it up again?
Dance o’er my lady lee,”
—Unknown. London Bridge (l. 1–6)
