In 1935 my father ended up working on a WPA project building a wall along the side of the road that went from West Nanticoke, Pennsylvania to the nearby summer resort of Lake Silkworth.
The wall is still there, protecting the river from wayward motorists and the road from a wayward river...
This job must have been quite a shock to an unemployed 19-year-old grocery clerk.
To get an idea of the size of this Work Projects Administration [WPA] project, look at the photograph with the pedestrian. The wall is much longer than shown in these 2011 pictures, but there was no other safe place to pull over.
