Project Limits

Note: In late winter, the northbound Route 1 left turn lane to Annapolis Way will be closed for about three weeks to reconstruct the intersection. Traffic will be detoured via northbound Route 1, a u-turn at Furnace Road and southbound Route 1 back to Annapolis Way.

Route 1 (Jefferson Davis Highway) is being widened from four to six lanes between Marys Way and Annapolis Way. 

The project also includes:

  • Enhanced access to the Woodbridge Virginia Railway Express kiss-and-ride facility
  • A new Route 1 bridge at Marumsco Creek
  • Improvements to Occoquan Road, including a median and turn lanes from Route 1 to south of Horner Road
  • Additional through and turn lanes on Route 1 and Occoquan Road to improve traffic operations
  • A ten-foot shared-use path and six-foot sidewalk
  • Demolition of several vacant buildings along the corridor

Route 1 averages 38,000 vehicles a day within the project limits. 

Estimated Costs
Preliminary Engineering: $11 million
Right of Way Acquisition and Utility Relocation: $97 million 
Construction: $56 million
Total: $165 million

This project is financed with federal, state and county funding.
