NVTC leads the planning process for Envision Route 7, a project making bus service even better on Route 7 between Tysons and Alexandria. Better bus service will benefit riders, nearby businesses and even the people who choose not to ride but benefit from the promise of less traffic congestion.
Route 7 is a diverse, vibrant corridor that spans 14 miles and four jurisdictions: (Fairfax County, Falls Church, Arlington County and Alexandria). It’s also a busy transit corridor currently served by 40 bus routes at various points, including the F20 Metro Bus, which has the highest ridership in Northern Virginia with more than 2 million trips per year. Envision Route 7 will make buses even faster and more reliable along this route.
The project will:
Envision Route 7 is at a pivotal moment, one that will determine how years of thoughtful planning move into the design and operational phase. Improvements along Route 7 are already happening, including transit signal priority treatments, projects to increase bus speeds, and new limited stop service along the corridor, including the upcoming launch of the Commuter Choice funded Metro Bus F2X route.
Longer-term changes to the route require coordination of multiple cities, counties and partner agencies, such as VDOT and Metro.
Project partners, with consultation from the community, are deciding what form of bus priority works best for their respective segments of Route 7.

What is bus rapid transit?
Bus rapid transit (BRT) is a high-quality, bus-based public transit system that is designed to deliver fast and efficient service.
BRT may include dedicated lanes, traffic signal priority, off-board fare collection, elevated platforms and enhanced stations.
Designed with rail-like features such as dedicated lanes, BRT can deliver fast, frequent and reliable transit service along a fixed route with the flexibility of a bus.
Phase 4-2: Mobility Analysis-Seven Corners to Mark Center/Southern Towers Transit Center (2026)
NVTC and partners are currently examining the findings from Phase 4-2 and expect to release a report this winter.
The Phase 4-2: Mobility Analysis will examine the segment from Seven Corners in Fairfax County to the Mark Center/Southern Towers in Alexandria, completing the corridor’s mobility analysis.
This phase supports NVTC’s Envision Route 7 Strategic Implementation Plan strategy to identify near-term, targeted enhancements to existing bus service on Route 7 and detail opportunities for funding those improvements, while continuing to lay the groundwork for the more capital-intensive work ton Route 7 in the future. Phase 4-2 will build off previous analysis by NVTC and the Fairfax County Department of Transportation and include the following study objectives:
- Identify trends and examine issues related to traffic congestion by collecting and analyzing data to understand the operational impacts of center running vs. curb running bus lanes along the study corridor.
- Facilitate community conversations around bus rapid transit on the project corridor.
- Conduct further analysis in the City of Falls Church regarding Business Access and Transit (BAT) lanes, including queue jump opportunities.
- Resolve the southern terminus of the Envision Route 7 corridor in Alexandria (Southern Towers vs. Mark Center).
Phase 4-2 began in May 2025 and will be completed in December 2026.
Phase 4-1: Mobility Analysis-West Falls Church Station to East Falls Church Station (2023)
Phase 4-1, led by NVTC and completed in fall 2023, provided a detailed mobility analysis of approximately 3.5 miles of the project corridor from just south of I-66 through the City of Falls Church and Arlington County to Seven Corners. The study developed three bus priority scenarios that document a range of improvements to bus operations along the segment. NVTC is working closely with the City of Falls Church and Arlington County to integrate the bus priority treatments identified in Phase 4-1 into their own jurisdictional plans.
This phase was conducted by Fairfax County. In 2023, the Fairfax County Board of Supervisors formally adopted Route 7 (BRT) in the Comprehensive Plan, endorsing bus priority infrastructure from Spring Hill Station, via International Drive to Route 7, continuing south to I-66 and reaching West Falls Church Station. NVTC considers this work along the western portion of the corridor as Phase 4-0, placing it within the ongoing planning efforts that evaluate geographic sections of the corridor. In this portion of the corridor, Fairfax County plans to implement median running lanes on Route 7 and International Drive, use business access and transit (BAT) lanes on the Spring Hill Road and Tyco Road couplet, and operate in mixed traffic in the remaining segments around Tysons. This infrastructure plan will require the widening of Route 7, from four lanes to six lanes, from Haycock Road to I-495 to maintain existing service commitments.
Phase 3: Conceptual Engineering (2019)
Phase 3 was a conceptual engineering study that refined the project cost, identified potential areas of concern and provided guidance on preserving the required right-of-way. It developed planning-level drawings of the BRT alignment, right-of-way requirements and roadway design along the corridor. By identifying right-of-way that would be utilized by the BRT, this phase informed jurisdictions in their land-use planning.
Phase 2: Alternatives Analysis (2017)
The Alternatives Analysis determined which mode of travel would best serve the Route 7 corridor and where and if the bus rapid transit (BRT) system should deviate from Route 7.
The study concluded that BRT along Route 7 from Tysons to the Mark Center/Southern Towers in Alexandria, via the East Falls Church Station and Seven Corners, is a viable transit solution for the corridor.
This phase:
- Estimated the potential demand and forecast the ridership.
- Compared possible alternative modes, such as light rail (LRT).
- Determined possible funding mechanisms and strategies
- Provided an initial cost estimate for capital and operating costs.
The study found that BRT would serve ridership across all trip purposes for less cost than LRT. The BRT service would provide commuters with key connections to Tysons, Mark Center/Southern Towers, and Metro as well as provide access for shopping and recreational trips.
Phase 1: Setting the Stage (2013)
Setting the Stage was a high-level planning effort that identified needs along the corridor, the context of the corridor and initial alternatives that could be explored in later phases.
NVTC works closely with Alexandria, Falls Church, Fairfax County and Arlington through the project development process.
