Maximum Tarmac Curvature

Just how curvy does a road have to get before it’s too curvy? Though opinions will vary, I’m sure, I have to guess that, from a civil engineer’s perspective, the Palms to Pines Highway must be pushing the limits.

Climbing Telegraph Hill on foot means stairs. Lots and lots of stairs.

Climbing Telegraph Hill by car means loops. Lots and lots of loops.

(Though I’m sure my memory is exaggerating.) On that winding road through the trees and stones, under the watchful eyes of the wild parrots, are occasional glimpses of the Golden Gate Bridge. With the last wisps of sunlight landing on the hill, the craggily texture of the tarmac and the rocks and trees contrast so perfectly the with the far-off Platonic idealism of that bridge.
