Connecting roads PA 33, I-476 & PA 61
Developers have been buying up farms and building distribution centers = Tractor Trailers -> lots of Tractor Trailers
Note PA 100 Sam Adams Brewery - going west - chill out and go with the flow
PennDOT decided to add lanes and "fix / modify" bridges of 1-78.
There are times of day when there are more tractor trailers than cars. Construction zones, trucks to be in left lane [they usually are] and speed limits are usually 55 mph. Your experience may vary.
Keep the shiny side up & the dirty side down!
