The nine-mile western stretch of the E-ZPass Express Lanes spans from Route 29 in Gainesville east to Route 28 in Centreville. The lanes feature multiple new ramps providing access to and from the E-ZPass lanes. The remaining 13 miles of new E-ZPass lanes on I-66 between Route 28 and I-495 (the Capital Beltway) should open in December 2022.
