Philadelphia's Camac Street used to be paved in wood - now the city is returning it to its roots
Camac Street in Philadelphia was once paved with wood, but covered up with asphalt in 2015 ahead of Pope Francis' visit and Mass on the Benjamin Franklin Parkway. Now the city is bringing the wood paving back, making Camac the only street in the city and one of a few in the United States paved with wood.
