Sudden Lane Narrowing at Upper Esentepe Bend

Upper Esentepe Mountain Road | Late Afternoon Descent

Along the descending section of the upper Esentepe mountain road, one particular bend tightens more than drivers anticipate. The approach feels wide. The exit does not.

The exposure is perceptual compression.

As vehicles descend toward the coastal road between 16:30 and 18:30, light begins shifting from overhead to lateral. Shadows from retaining walls stretch across the asphalt. Depth cues change.

The lane appears consistent in width on entry. However, the inner curve subtly reduces usable space due to stone edging and natural slope encroachment. There is no formal shoulder.

A repeated local pattern occurs when a descending vehicle maintains steady speed through the bend while an ascending vehicle approaches simultaneously. Both drivers assume the other will hold a perfectly centered line.

The road allows little correction margin. Side mirrors become the first point of vulnerability.

This is not excessive speed.
It is the assumption of symmetry on an asymmetrical bend.
