These are Fairmount Park WPA-era maps altered by Park engineers in the mid-1950s to show the prospective course of the Schuylkill Expressway through Park lands. If you look below the whitewash you can see springs, monuments, and whole watersheds soon covered by bands of steel and concrete. This is near the Montgomery Ave. exit south of the Horticultural Center.
Just a little bit heartbreaking.
yes but so gorgeous!
