[Updated 8/13/2015] Sarah Laskow writes about the Old Spanish Trail, completed in 1929 as "2,743 miles of brick, asphalt, concrete, and wooden plank, [crossing] the southernmost states from East to West, starting in St. Augustine, Florida, and ending in San Diego, California."

According to Laskow, the Old Spanish Trail is mostly a ghost road now, but an organization called OST100 is working to restore the road to its "former vigor" as "the kind of road people fantasize about traveling from end to end."

The article includes a lot more detail about the history of the road, its current state, and what it will take to restore the road in time for its 100-year anniversary.
