Average Hourly Traffic

Based on current and historical average month and average day traffic data, these graphs show the directional hourly traffic volumes across the Glenn Jackson Bridge (I-205).

Wave your mouse over the list of years to the right of the graph, to get a “time lapse” view of how the hourly traffic patterns have changed over the years.

Average hourly traffic data for the Interstate Bridge (I-5) are also available. Hourly traffic counts were provided by the Oregon Department of Transportation, which maintains permanent traffic recorders on the south ends of both bridges.
