Highways in FL are jammed per Google Maps app. Wow..
I used to drive from Sarasota to NY and I had several people tell me on different occasions to not bother with I-95 or I-75 but rather to take 301 north to Jacksonville.
They said it was actually faster than I-95 just on an average daily basis even though it goes through some small towns with speed zones.
I just looked at Google traffic and 301 shows green all the way.
