The Chasm, or Neahkahnie Mountain, Bridge was completed in 1937. The bridge is a concrete girder bridge with arched outer facia walls. Designed by Glenn S. Paxson, its concrete masonry and railings stretches over Highway 101 near Cape Falcon. Located at mile post 40.71, the bridge’s railings extend nearly uninterrupted around Neahkahnie Mountain along one of the most beautiful sections of the Oregon Coast.
