Directions to TLC’s Walnut Hill Headquarters

As many people know, the Chandler Mill Bridge was recently designated for pedestrian and bicycle-only use, and part of the Red Clay Greenway Trail System, by Kennett Township after a decade of advocacy to preserve it. While we’re celebrating the preservation of a quiet back road and nature preserve, many outdated GPS systems haven’t heard the news, which has led to some confusion when trying to get to TLC’s Headquarters. Please use this map of key area roads to help make your way to 541 Chandler Mill Road via Hillendale from any direction. Enjoy the view!
