The pipes down below

To get to the pipes down below,
they first had to tear up the road
that carried each heavy wide load
and more cars that can ever be told.
Those men with their pickax and drills,
orange vests, digging loadly and still
digging deeper. The whole messy task
caused my son, as we drove past, to ask
 "Mom why are they breaking the road?
It's such a big mess, and I'm cold."
I told him all that I could tell
from not knowing roadwork too well,
"Son, to fix all the pipes down below,
they first had to tear up the road."
