I-605 crash-record density
Adjust the window from the profile start date. The map redraws to show only loaded mappable records inside that date range.
How reported I-605 crashes compare by year
Annual counts use the same road-matching method as this profile. The latest year may be incomplete if the source data has not reached year end.

Sideswipe Context
Of the sideswipes with clear lane details, 634 crossed multiple reported lanes (lane-departure context), while 99 occurred within a single lane.
Note: Lane numbers are officer-reported (e.g. "Lane 1" is typically the fast lane). They are useful for local review but do not reflect verified road geometry.

How this corridor profile is produced
No applied canonical mapping exists for I-605 yet, so this profile temporarily uses the legacy curated alias matcher against the officer-recorded primary-road label. The reporting window is 2025-10-23 through 2026-10-22. Source records come from the California Highway Patrol California Crash Reporting System.
Read the full methodology and privacy notesWhat the numbers cannot establish
- Raw crash counts do not measure individual risk or identify the “most dangerous” segment.
- Traffic volume, vehicle miles traveled, road length, construction, and enforcement exposure are not controlled here.
- Road and city labels can be incomplete, inconsistent, or revised after publication.
