It's Time to Fix I-66!
VDOT Seeks Public Input on
I-66 Outside the Beltway

The Virginia Department of Transportation is seeking public input on its Tier 2 Study of the proposed improvements to Interstate 66 outside the Capital Beltway (from I-495 to Rte. 15 in Prince William County).


The Tier 2 study shows that the I-66 corridor requires a bold solution that combines additional road capacity with phased transit enhancement/expansion to address current congestion and the forecast growth in population (32%), jobs (68%) and auto trips (10-66%) in the corridor over the next 25 years

As proposed, the I-66 Corridor Improvements Outside the Beltway (1-495 to Rt. 15) include:

  • Two managed Express lanes in each direction for toll, HOV3 and transit
  • Three conventional lanes in each direction with a hardened shoulder
  • Reservation for future transit extension
  • Additional and expanded park-and-ride lots
  • Expanded and enhanced commuter bus service to multiple employment centers*
  • New rapid bus service* in the express lanes, running all day, both east and west bound, Monday through Saturday (with addition of Sunday service in the out years as demand grows).

*To be phased in by 2040 with forecasted demand

Upgrading the I-66 corridor with new Express and conventional lanes and transit options is essential to our region's economic competitiveness and quality of life

Yet, adoption of this approach is not guaranteed. Many seek to drastically reduce or kill the plan altogether. If those efforts succeed, I-66 will be gridlocked in perpetuity.

This is our best and perhaps last chance to Fix I-66 right for the future.
