Traffic Signals and Signs
Traffic Signals
The Township maintains 46 signalized intersections, 14 school signals and 1 flashing warning device.
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 to the timing or operation of any signal should be submitted in writing to publicworks@tredyffrin.org or to Tredyffrin Township Public Works Department, 1100 DuPortail Road, Berwyn, PA 19312.
Signs
The installation and maintenance of traffic signs (regulatory, advisory, warning, informational, etc.) is the responsibility of the Township on its roads. The justification and location of signs is directed by the Manual of Uniform Traffic Control Devices (MUTCD) http://mutcd.fhwa.dot.gov/ which the Township follows. New sign installation requests are reviewed by the Traffic Committee. Traffic lines, crosswalks and intersection pavement markings are repainted on a yearly basis and some intersections have more permanent thermoplastic markings.
Signs on Pennsylvania Department of Transportation (PennDOT) http://www.dot.state.pa.us roadways are PennDOT's responsibility. Exceptions to this are speed limit signs of 35 MPH and below and signs required under a traffic signal permit are Township responsibility.
Due to the growth of vegetation over time, signs can become blocked rendering the sign useless and possibly creating a hazardous condition. It is the property owners responsibility to keep their vegetation trimmed to allow full visibility of traffic signs.
Pavement Markings
A schedule of line painting will be posted in the current events and projects section of the Public Works portion of the website.
All requests for installation and maintenance of signs or questions about traffic lines and markings should be directed to the Township at (610) 408-3620 or publicworks@tredyffrin.org or by letter to Department of Public Works at Tredyffrin Township, 1100 DuPortail Road, Berwyn, PA 19312.
