Volumes are based on the total number of vehicles entering an intersection on an average weekday, and are approximate due to the variability from year to year, month to month, and day to day. Freeway ramp intersections with streets, were not considered for this listing. Intersections are counted once every two to three years, and this list is based on the most recent count available.
Links in the first column (rank) of the table below will take you to that specific intersection. Links in the second and third columns (street names) will take you to an index for that arterial.
