The Reading Viaduct lost one its most passionate advocates last week with the sudden passing of Paul vanMeter. On February 6 vanMeter died of natural causes at the age of 54. In addition to his diverse work as a landscape gardener, writer, and artist, Paul vanMeter was a visionary force behind VIADUCTgreene, a nonprofit dedicated to imagining a new future for three miles of the Reading Viaduct in Philadelphia.
