***** NOTICE *****

The "Pardon Our Dust" meeting detailed in this release regarding construction of the utilities ductbank scheduled Thursday, Feb. 26 in Woodbridge has been POSTPONED due to inclement weather. Once a rescheduled date has been determined, we will post it here.

About the Project

The intersections along Route 1 at Route 123 and Occoquan Road operate at capacity during peak periods, and are expected to operate at unacceptable levels in the future without the planned improvements. In Phase 1, this project will widen Route 1, and add turn lanes along Occoquan Road. Planned Phase 2 improvements include building Route 123 over Route 1 and the CSXT railroad, widening Route 123 and making several other intersection improvements to significantly improve traffic flow. 

In Phase 1, Route 1 will be widened from four to six lanes between Mary's Way and the approach to the Occoquan River Bridge. Occoquan Road will also be improved with median and turn lanes from the Route 1 intersection to south of Horner Road. The signal at Route 1 and Occoquan Road will remain and traffic operations will be improved by the additional through and turn lanes on both roads.

The proposed project provides enhanced access to the Woodbridge VRE/Amtrak Station for vehicles, bikes and pedestrians during the project's first phase. It also constructs an important segment of the Potomac Heritage National Scenic Trail from the intersection at Route 123 and Annapolis Way to the Belmont Bay community.

In advance of the Phase 1 Route 1 Widening project, and beginning in March 2015, an underground Ductbank for utilities along Route 1 will be constructed and buildings in the path of the Ductbank will be cleared and demolished.

In Phase 2, the new interchange will build Route 123 over Route 1 to separate through traffic, and connect Route 123 to Belmont Bay Drive east of the railroad. Route 123 will be widened from four to six lanes from the Route 1 interchange to just east of the I-95 interchange, and Express Drive will be raised to connect to the new Route 123/Belmont Bay Drive. The project will eliminate two signalized intersections on Route 1 at Route 123 and Annapolis Way. 

These improvements will allow Routes 1 and 123 to operate at acceptable service levels through 2036.

Route 1 currently carries approximately 35,000 vehicles per day and Route 123 carries about 21,000 vehicles per day. Projected volumes for 2036 are 75,000 vehicles per day on Route 1 and 36,000 on Route 123.

Project Features

Some of the project's features include: 

  • Raised grass medians on Route 1 between Mary’s Way and the Occoquan River, and on Route 123 over Route 1 to Belmont Bay Drive
  • A new Route 1 bridge at Marumsco Creek
  • A ten-foot shared-use path and a six-foot sidewalk on both Routes 1 and Route 123 
  • Utilities along the Route 1 corridor will be placed underground.

Route 1 intersection at Occoquan Road/Dawson Beach Road will be improved by:

  • Additional thru lanes on Route 1
  • Double left turn lanes on northbound Route 1 to Occoquan Road
  • Double left turns on southbound Route 1 to Dawson Beach Road
  • Additional turn lanes on Occoquan Road

Project Schedule

2011 - Public hearing held
2012 - Began right-of-way acquisition
March 2015 – Begin construction of underground Utilities Ductbank
2016 – 2018 - Phase 1 road construction: widen Route 1 and improve Occoquan Road
TBD  - Phase 2 road construction – Route 1/123 Interchange and Route 123 Widening  (schedule to be determined, pending funding)

VDOT’s current plans are to build the project in phases.  In preparation for the road construction projects, right of way acquisition is being completed, and construction of an underground Utilities Ductbank is scheduled to start in March 2015, which will include demolition of buildings in its path. Phase 1 road construction would widen Route 1 and make improvements to Occoquan Road, with construction anticipated to start in early 2016. The remaining Route 123 improvements and proposed interchange (Phase 2) would be constructed when additional funding has been identified.

Estimated Costs

Preliminary Engineering: $14.6 million
Right of Way: $86.6 million
Ductbank: up to $12.1 million (design/adjustments/construction)  
Roadway Construction: $145.7 million
Total: $259 million
