Most Traveled Principal Arterials

Twenty-four urbanized areas had 779 miles of principal arterial highways that operated at a level of 200,000 or more vehicles per day. A table on the website summarizes by route the amount of Interstate and other freeways and expressways that carried 200,000 or more vehicles a day, and the highest daily traffic reported for the route. About 48 miles of these highways carried at least 300,000 vehicles a day. The highest daily traffic of 365,852 vehicles a day was reported along a 12-lane section of I-5 in Orange County, California. On non-Interstate segments, the highest daily traffic of 320,283 vehicles a day was reported along a 10-lane section of U.S. 101 in Los Angeles County, California...
