Report: Nearly half of I-66 corridor commuters carpool or use transit

Nearly half of the Northern Virginia commuters heading toward D.C. each morning on the Interstate 66 corridor use transit or ride sharing to get through the notoriously clogged region, according to a new report.

The study released this week by the Northern Virginia Transportation Commission counted the stream of commuters headed inbound at various points along a north-south line just outside the Beltway, creating a snapshot of the commuters on the highway itself plus other roads and transit modes.
