Changing Skyline: Philadelphia's only surviving wooden street embalmed in asphalt

Philadelphia is a city where the streets are paved in gold, as well as occasionally in hues of blue, red, and orange. We are talking bricks, and there is probably no place in America that can boast such a rainbow of paving colors, materials, and textures. You can find dozens of streets surfaced in Belgian block, cobblestone, riverstone, and bluestone.
