North Euclid Avenue Climb from South Euclid Avenue near Upland

We don't rate roads as safe or unsafe: crash counts can't say how risky a ride is, and roads people like to ride draw more riders, so they see more crashes. The records here are also incomplete: most reports along it are filed under Upland, where only 55% of reported bike crashes have a map location, so the numbers here are too low. What the records show: 4 bike crashes were reported on or beside North Euclid Avenue along the climb from 2021–2025.
