Highway 41, Revisited

Expansion of my haiku "Highway 41," took a note from Dylan on the (working) title

The stretch of old Highway 41
between Rockville and Bloomingdale
is a series of switchbacks
twisted as sidewinder tracks,
the tar and asphalt scales
basking in the summer sun
as often as the trees permit.
Crawling through the countryside
it runs sideways north and south,
alternating two and four lane mouth.
Sloughed off exits, skin that's died,
are roads to places that cannot fit
along this serpent's twisted tracks
of tar and asphalt scaled switchbacks.
