Traffic Volumes on I-495 Northwest

For each directional highway segment included here, several diagrams are presented that show, in turn, average weekday daily traffic (AWDT) volumes, and peak period hourly volumes from 6:00 AM to 10:00 AM and from 3:00 PM to 7:00 PM. The AWDT volumes are shown for a year during the period 2003–2007, and for any previous years that the individual highways and their ramps were counted. Historical AWDT information is available in some cases from as far back as 1974. AM and PM peak period hourly volumes are presented for the latest year during which individual highways and their ramps were counted.
