Traffic Signals
The Township has 46 signalized intersections, 14 school signals and one flashing warning device for which we are responsible to install, operate and maintain.
All the above devices are permitted by the Pennsylvania Department of Transportation (PennDOT) and updates and/or changes must be reviewed and approved by the local PennDOT office in King of Prussia. This process can take many months depending upon the degree of changes and amount of work or cost. The Township contracts with a private contractor for annual checkup and ongoing maintenance of the signals.
Traffic signals not working should be reported to the Public Works Department at (610) 408-3620, publicworks@tredyffrin.org, or by filling out the online form.
Requests for changes or noted problems with the operation should be reported (preferably) in writing to publicworks@tredyffrin.org or to Tredyffrin Township Public Works Department, 1100 DuPortail Road, Berwyn, PA 19312.
