Crash Information A GCAT spatial query was run from log point 17.90 to log point 18.20 on US-422 from 2014-2016. The query identified a total of 13 crashes. All crashes were reviewed and hand logged revisions were made where needed. Three crashes were removed from the analysis; two animal crashes and one crash that occurred outside the study limits. Of the remaining 10 crashes, 3 were corrected for log point. The following tables represent the breakdown of total number of crashes per year, type of crash, road condition, crash severity, day of the week, and time of day.
