Pittsburgh Street the Last of its Kind in U.S.
You might be surprised to see what it's made of.
It's the last of its kind in the U.S.: a road made entirely of... wood.
That's right, Roslyn Place in Pittsburgh's Shadyside neighborhood is paved entirely from wooden blocks. Now, obviously, the PA Dept. of Transportation doesn't specialize in wooden road maintenance (would that be considered carpentry?), so how has this road survived these past 105 years?
Watch here as I went to the neighborhood to check it out:

The neighbors are such good stewards of the street that they have stockpiles of wooden blocks to make repairs when the need arises.
The street is made up of roughly 26,000 wooden blocks just like this one
The wood block street was designated as a City Historic Landmark in 2015 and the homes around it were designated as a City Historic District in 2018. But the journey into the history books doesn't stop there; Roslyn Place (the neighborhood and the street) is currently being considered by the Pennsylvania State Preservation Board as the second step towards being listed on the National Register of Historic Places.
