ASPHALT ON WOOD (Rt 66 San Jose NM)
This image won't be a big seller...but it has documentary value. They're not nailing together boards for bridge decks anymore, at least not on the US highway system! Over the wood, a layer of asphalt was spread.
This narrow 1921 truss bridge is closed and abandoned but can still be walked. This was Route 66 until 1937.
