Here's a great list of frequencies:

LOOK UNDER " DOT frequencies"
way down the bottom of this list!

load up the FRS and the 154.600 154.57 151. 625 and the other
itinerant frequencies

And look up the company's name (or if they are a "townie" DPW out fit) that's
on the side of the
construction trucks. If there is just a telephone number with out town or
address,
do a reverse telephone number look up on the web for the name then
look them up here

I have herd town DPW flag crews using
the itinerant frequencies. In stead of their licensed High Way frequencies!

Be more specific. For what city/state? Some road crews are on low
band, and I understand some even use itinerant freqs.

haven't stumbled upon the right frequencies. Do they use Motorola radio?
What would those frequencies be? Thanks.
