Quick Answer: What Changed for Loudoun Commuters in 2026?
If you are shopping for a home in Loudoun County, your commute budget matters as much as your mortgage. A 14-mile private toll road, a publicly owned toll road, express lanes, and three Metro station garages decide what getting to work actually costs. In 2026, every one of them moved.
The Greenway Toll Fight: $5.80 to $6.75 at Peak
Quick summary: the Dulles Greenway's private operator wants peak tolls up from $5.80 to $6.75 and off-peak from $5.25 to $5.60; the State Corporation Commission has not decided. The Dulles Toll Road's 2025 revenue fell 2.3% to $198.4 million, which could bring a rate increase earlier than expected. VDOT revived the I-495 Southside Express Lanes plan on September 22, a new I-66 slugging network launched this fall, and Loudoun County is adding fare gates to its two Metro garages.
The Dulles Toll Road: Revenue Down, a Hike Could Come Early
## The Greenway Toll Fight: $5.80 to $6.75 at Peak
Express Lanes: Southside Revived, McLean Open, I-66 Slugging Launches
The Dulles Greenway is a 14-mile privately owned limited-access highway connecting Leesburg to the Dulles Toll Road (FOX 5 DC, June 2026). Its operator, Toll Road Investors Partnership II (TRIP II), asked Virginia's State Corporation Commission to raise peak-hour tolls from $5.80 to $6.75, a 95-cent jump, and off-peak tolls from $5.25 to $5.60 (Loudoun Now, May 1, 2026).

The pushback was fast. The Loudoun County Board of Supervisors voted in May 2026 to intervene, the county Chamber of Commerce asked the SCC to deny the hike (FOX 5 DC, June 2026), and Congressman Suhas Subramanyam wrote the SCC on July 1, 2026 citing the 2021 Virginia law he authored that lets the SCC block increases which would materially discourage use of the road. The SCC held a public hearing June 29, 2026 at Rock Ridge High School in Ashburn and took written comments through August 12.

Context matters. The SCC rejected an earlier TRIP II proposal for a 40% increase, and the Supreme Court of Virginia upheld that denial on July 17, 2025 after the Attorney General's office intervened. That blocked hike would have cost daily commuters more than $1,100 a year (Virginia Office of the Attorney General; Subramanyam's July 2026 letter). As of September 24, 2026, the SCC has not ruled on the new request, so current tolls stand.

## The Dulles Toll Road: Revenue Down, a Hike Could Come Early
Sources and Next Step
The Dulles Toll Road is the public side of the corridor, run by the Metropolitan Washington Airports Authority (MWAA), and its tolls back the debt on the Silver Line extension. In May 2026, MWAA reported 2025 toll revenue of $198.4 million, down 2.3% year over year. Lower-than-projected use and revenue could trigger a rate increase earlier than the previously anticipated 2028 time frame (FFXnow, May 21, 2026).
## Express Lanes: Southside Revived, McLean Open, I-66 Slugging Launches
On the Beltway, VDOT briefed Fairfax County's Transportation Committee on September 22, 2026 with a revived design for the I-495 Southside Express Lanes: 11 miles of toll lanes from Springfield across the Woodrow Wilson Bridge into Maryland, engineered to leave room for future Metrorail service on the bridge (FFXnow, September 24, 2026). It is a planning step, not construction.
The northern I-495 Express Lanes extension in McLean opened November 23, 2025, adding two toll lanes each direction (FFXnow, November 21, 2025). On I-66, the I-66 Slugging Network, a coalition of residential groups and public agencies, launched in September 2026 to organize slugging: drivers pick up passengers so the car qualifies for HOV lanes and both skip the toll (FFXnow, July 27, 2026).
## Commuter Parking: Fare Gates Coming to Loudoun's Metro Garages
Loudoun County operates two Metro parking garages, Ashburn Station South and Loudoun Gateway, while the Ashburn North garage is privately run (loudoun.gov). Ashburn South has 1,540 spaces at $4.95 a day, and the three station garages together hold nearly 5,000 spaces (loudoun.gov, 2022). In 2026 the county is adding fare collection gates at both county-operated garages, with its $45 to $65 monthly reserved-parking program evolving as the gates go in.
## What Commute Costs Mean for Loudoun Homebuyers
Run the commute math before you pick a neighborhood. At today's Greenway rates, a peak-hour commuter pays $5.80 each way, about $2,900 a year over 250 working days. The proposed $6.75 peak would make it about $3,375, roughly $475 more. Add the Dulles Toll Road each way and it climbs again. For Leesburg and western Loudoun buyers who drive the corridor daily, the gap between Greenway-dependent and Metro-accessible locations is thousands of after-tax dollars a year. When we tour Loudoun with buyers, we price the commute like a second HOA.

FAQ: Loudoun Commuter Garages and Tolls
FAQ
Is the Dulles Greenway toll going up in 2026?
Not yet. TRIP II asked the SCC to raise peak tolls from $5.80 to $6.75 and off-peak from $5.25 to $5.60. Loudoun County officials and Congressman Suhas Subramanyam oppose it. The SCC held a public hearing June 29, 2026 in Ashburn and took comments through August 12. As of September 24, 2026, no decision has been announced, so current tolls stand.
How much does a daily Greenway commute cost per year?
At current rates, a peak-hour commuter pays $5.80 each way, about $2,900 a year over 250 working days. Under the proposed $6.75 peak, that rises to about $3,375 a year, roughly $475 more. Those figures exclude the separate Dulles Toll Road toll each way.
Where can I park to take Metro from Loudoun?
Loudoun County operates the Ashburn Station South garage (1,540 spaces, $4.95 a day) and the Loudoun Gateway garage; Ashburn North is privately run. In 2026 the county is adding fare collection gates to both county garages. A $45 to $65 monthly reserved-parking program is also available.
What is slugging on I-66?
Organized carpooling: drivers pick up passengers at commuter lots so the vehicle qualifies for HOV lanes and both skip the express-lane toll. The I-66 Slugging Network, a coalition of residential groups and public agencies, launched in September 2026 along the corridor.
