Blackwing Volume 746 Golden Gate Bridge Pencils (set of 12)

In the summer of 1929, the newly-formed Golden Gate Bridge and Highway District hired Joseph B. Strauss to complete a task that many said was impossible: build a bridge across the churning waters of the Golden Gate Strait. He and his team of engineers, designers, and planners used pencil and paper to develop the sketches, design drafts, and finished plans that would become the Golden Gate Bridge. When the Golden Gate Bridge opened on May 27, 1937, it was the longest suspension bridge in the world. It measured 1.7 miles long, with a 4,200-foot main span and two 746-foot towers supporting the structure at either end. The innovative engineering techniques used to build the bridge have allowed it to withstand hurricane-force winds, raging ocean currents and the rumblings of the nearby San Andreas Fault. The Blackwing 746 features Blackwing’s firm graphite core and is finished with a special multi-layered technique to bring out the iconic International Orange color of San Francisco’s world-famous marvel.
