Cabrillo Highway (SR-1) Carmel Highlands to Big Sur
At a glance: Graded 86 out of 100 (Tier 4: Steep Mountain & Exposed Coast) across 18.5 miles in Central Coast. Exposed two-lane coastal cliff alignment with scenic pullout conflicts, crosswinds on high arch bridges, and zero median separation.
Why this corridor sits in Tier 4
Carved into coastal headlands above the Pacific Ocean, SR-1 between Carmel Highlands and Big Sur pairs steep ravine descents and climbs with sudden braking near unpaved scenic turnouts at Bixby Creek Bridge and Hurricane Point. Fog banks, gusting onshore crosswinds, and zero median buffer magnify sightline and lane-keeping demands.

Methodology & interpretation limits
Complexity Index combines horizontal curvature, sustained elevation grade, speed-transition demand, and 12-month historical reported crash concentration per corridor mile. Counts describe observational public records unadjusted for daily traffic volume and do not represent driving safety advice. Missing-coordinate collision records in surrounding cities are reported separately in live buffered queries and are never plotted at synthetic coordinates.
