The CR-510 Bridge is a unique treasure of engineering mastery in the form of a truss bridge. This massive steel span of riveted trusses moved from its original home over the Allegheny River in Pennsylvania to its current location crossing the Dead River in 1939. Pennsylvania truss bridges such as this one are a special type of construction built to extend across great distances. As of 2010, the CR-510 Bridge is a historic monument to the fine craftsmanship and engineering marvels created by America’s great bridge builders. The bridge no longer handles every day traffic but is open to pedestrians, explorers, and engineering admirers.
