CHARLES Co MdTA Nice Bridge??

[TopFlite]

Can anyone in Charles Co able to hear or in a position to know, tell us whether the MdTA Police at the Route 301/ Harry Nice Bridge are currently using 453.97500 [127.3] or are on the TG 18880 as listed in the DB?

I can confirm that they are still using 453.975 as of about a minute ago, heard from my location in La Plata on a BC60XLT with stock antenna.

Sorry, I'm a dinosaur and don't on a trunking scanner so have no idea if the talk group listed is being used in parallel.
