Sacramento's Old Sacramento air quality reflects the historic Gold Rush waterfront district, with vehicle traffic on the surrounding I-5 and the Sacramento River providing local sources. The I-5 expressway's concentrated freight and vehicle traffic generates elevated diesel PM2.5, while the Sacramento River provides limited ventilation and Old Sacramento's historic character and the river waterfront maintain moderate Sacramento metropolitan readings throughout most of the year.
