The Route 7/Route 659 (Belmont Ridge Road) project provides for the design and construction of an interchange at the intersection of Route 7 (Harry Byrd Highway) and Belmont Ridge Road. Please check back as the project progresses for updates. The project is expected to be completed in early 2019. 

Planned Bridge Work, Traffic Shifts & Detours Underway

Work that began March 27, 2018, has resulted in a traffic shift as part of preparations for a significant milestone of the Route 7-659 interchange project: the first phase of the opening of the interchange bridge. The work will eliminate the traffic signal on Route 7 and relocate Belmont Ridge Road northbound and southbound traffic onto the bridge. 

During the initial traffic shift, detours will be necessary to allow traffic to access Route 7 eastbound from Belmont Ridge Road and Belmont Ridge Road from Route 7 westbound. The first phase of the work is scheduled to begin on or about March 27, 2018, weather permitting, and is expected to last for two months. Motorists should expect delays during this period. If it is possible to use an alternate route during Phase 1 activities, please do so. 

What to Expect
Phase One Overview: The first phase opens traffic to the ramps and spurs on the west side of the bridge, eliminates the signal at existing Route 7, and puts Belmont Ridge Road traffic and the signal onto the interchange bridge. The Phase One traffic shift will allow the contractor to begin construction of the ramps and spurs on the east side of the bridge concurrently. This phase is expected to take about two months to complete and will require traffic detours onto Route 7 eastbound from Belmont Ridge Road and onto Belmont Ridge Road from Route 7 westbound.

Details of Phase 1 Construction Activity
Daytime Activities (9:00 a.m. to 3:00 p.m.)
  • Construction crews will be posted in all four traffic directions to facilitate the relocation of traffic barrels and temporary signage to allow for the traffic shifts.  This will include closure of right and left turn lanes of the Route 7 and Route 659 intersection, which is being removed.
  • The traffic signal on Route 7 will remain green to allow for the through movements of Route 7 eastbound and westbound traffic.
  • The traffic signal on the Route 7 & Route 659 interchange bridge will be activated and the bridge will be opened to allow for controlled movements on Route 659 northbound and southbound lanes and movements off of Route 7 eastbound onto Route 659 and off of Route 659 onto Route 7 westbound. 
  • Striping crews will be located north of the bridge to remove the former pavement markings and install new ones to realign Route 659 northbound, south of Promenade Drive.
  • Construction crews will remove the temporary wedge at existing Route 659 south of the interchange bridge using single lane traffic controlled by flaggers.  Striping crews will install temporary pavement markings to complete the realignment of both Route 659 northbound and southbound to and from the bridge. 
Nighttime Activities (10:00 p.m. to 5:00 a.m.)
  • Construction crews will be at the closed intersection of Route 7 and Route 659 to remove the traffic signal heads, traffic signals poles and arms, and associated signal equipment and cabling.  
  • Striping crews will be at the closed intersection to eradicate the former intersection striping and install the new pavement markings.
During nighttime activities, motorists on Route 7 eastbound and westbound can expect delays due to short-term temporary lane closures and one complete, short-term full road closure of Route 7 eastbound and westbound of no longer than 20 minutes.

Phase Two: The second phase will open traffic to the ramp and spur at the southeast corner of the interchange, allowing access onto Route 7 eastbound from Belmont Ridge Road and allowing the contractor to complete construction of the ramp at the northeast corner. The Phase Two traffic shift is planned to begin in May 2018 and should be completed within one month. Click here for a map of the detours that will be in place during Phase Two.

Blasting on Route 659 to Resume April 4, 2018; Blasting in Route 7 Median Continues 
Blasting along Route 659 (Belmont Ridge Road) that was scheduled to resume on or about Thursday, March 22, 2018, has been delayed due to the weather. It is now scheduled to resume on Wednesday, April 4, 2018, with the expectation that it will occur until  mid-to-late April 2018, weather permitting.  Once it resumes, blasting will be concentrated just south of the future intersection of Russell Branch Parkway between Gloucester Parkway and Route 7 to allow for the construction of the northbound lanes of Belmont Ridge Road.  

Meanwhile, blasting necessary for grading of the Route 7 median continues in the Route 7 median and is expected to be completed in late April. 

Blasting is generally scheduled to occur between the hours of 10 a.m. and 2:00 p.m. as conditions permit. The blasting may cause temporary road closures for brief periods, generally not longer than 20 minutes. All closures will be managed in accordance with Virginia Department of Transportation and Loudoun County requirements. All blasting will comply with the Loudoun County Fire Marshal’s requirements. Electronic message boards will be posted to advise the public of blasting.  

Loudoun County and the project team appreciate the community’s patience and attention to safety during construction!

Safety Reminder
Loudoun County issued a safety reminder when construction for the Route 7/659 Interchange project began. The project “Limits of Disturbance” are marked with stakes and white tape.  Signage and/or safety fencing visually advises people in the area of active construction.  Access to or through the project area is not permitted to ensure safety. This is particularly true for pedestrians in the vicinity. 

Groundbreaking Ceremony Held 

Loudoun County officials and other dignitaries gathered Tuesday, October 13, 2015, for a groundbreaking ceremony for the Route 7/Route 659 (Belmont Ridge Road) interchange and the widening of Belmont Ridge Road.

Notice to Proceed
In September 2014, the Loudoun County government issued a “notice to proceed” for the Route 7/Route 659 interchange and widening project. 

Contract Awarded
On May 20, 2015, the Loudoun County Board of Supervisors awarded the contract for the construction
of the interchange to Shirley Contracting in the amount of about $48.3 million. The Board item and the "Copy Teste," (the official record of the Board's action), are online:

The Route 7/Belmont Ridge Road (Route 659) intersection is currently an at-grade signalized intersection. The intersection is being designed for a grade-separated interchange in accordance with the Countywide Transportation Plan.

The project also includes approximately 1.4 miles of reconstruction of Belmont Ridge Road from two-lanes to a four-lane divided section from the interchange limits at Route 7 to Gloucester Parkway.

The Route 7/Route 659 Interchange project is funded through a combination of local, state and federal funds and in coordination with the Virginia Department of Transportation (VDOT). 

The Loudoun County Department of Transportation and Capital Infrastructure is managing the design and construction of the project. In addition to the county, the engineer of record is Dewberry, the general contractor is Shirley Contracting, and the consultant is McDonough Bolyard Peck, Inc. Questions on the project may be directed to the county via email.
