New I-66 Carpool Challenge Offers Free Rides and $1,000 Prizes
Fairfax, Va. – September 17, 2026 -- Commuters along Virginia's I-66 corridor can now skip tolls and save on gas through a new 66-day carpooling initiative called the I-66 Slugging Challenge, which launched Sept. 14 and runs through Nov. 20, 2026.
The program, organized by the I-66 Slugging Network, revives "slugging," a decades-old Washington-area tradition where drivers pick up strangers to meet HOV-3+ requirements and drive toll-free in express lanes, while passengers ride for free.
Commuters meet at two Park and Ride hubs to start their trips
Morning slug lines form at the Monument Drive Park and Ride in Fairfax and the University Boulevard Park and Ride in Gainesville, typically operating from 6:00 a.m. to 8:30 a.m. Riders are dropped off at four Washington-area destinations: Rosslyn, L'Enfant Plaza, Navy Yard, and Metro Center.
