PA Turnpike Frequencies
The main frequencies would be 159.045 and 159.075. These alternate as you travel down the Pike. I would also program 159.00, a car-to-car simplex channel that might be active at incidents. Finally, it might be a good idea to program 154.755, pl 186.2, which is the statewide mobile-to-mobile channel and might be used on the Pike or by aircraft.
You will hear state troopers, maintenance, toll plazas and tow trucks as well as EMS units on the main channels. Dispatch in all areas identifies as "Highspire", the main Turnpike headquarters near Harrisburg.
