Two bridges

Convergence at a distance confuses 
The mind's eye, maybe even the eye
Plain and simple, although there is
Nothing simple [or plain] about it,
The eye is complex and complicated.
The bridges converging to the north
Merge and blend running at parallel 
Tracks and turns, the shapes and the
Angles unique, distinctly different, 
Each going its own way, whichever 
Road it follows in a swoop or a semi
Circle, straight or narrow, there's a
Twist too, but you are too far away
And the converging roads confuse
