Route 50 Through Aldie Is Getting Another Roundabout. Here's the Timeline Residents Can Plan Around

On September 10, 2026, Loudoun County awarded the contract to build a roundabout at Route 50 and Everfield Drive in Aldie. The contractor is M & F Concrete, Inc., and the contract is worth $5,181,844.41. If you drive Route 50 between Gilbert's Corner and Stone Ridge, this is now the third major intersection change on your stretch of road in a little more than 15 years. It probably won't be the last before the decade is out.

Route 50 through Aldie is being rebuilt one intersection at a time so that the design of the road slows drivers down, and the county's bid documents name calming traffic as a goal of this newest project.

What the County Bought at Everfield Drive

Everfield Drive, state Route 3423, meets Route 50 today at an unsignalized intersection. The county's invitation for bid says the project will turn it into a single-lane roundabout. The approach roads will be realigned and widened where needed, and the work adds storm sewer and drainage upgrades, pedestrian facilities, new signs and pavement markings. The county's own bid document gives the reason:

"The Project is part of the County's ongoing efforts to improve safety, traffic flow, and access along the Route 50 corridor in Aldie, Virginia... this intersection serves a growing residential area and is experiencing increasing traffic volumes. The roundabout is intended to reduce crash risks, calm traffic, and enhance operational efficiency at a key access point for local neighborhoods."

That language comes from the county's Everfield bid solicitation. The phrase that matters most is "calm traffic." The roundabout is meant to change how drivers move through this point on Route 50, and helping turning traffic from Everfield is only part of the job.

Compare it with the Trailhead Drive roundabout to the west, which the county finished in 2025. Loudoun's January 2024 construction presentation showed a bigger design there. Westbound Route 50 got two lanes, one for left turns and one for through and right turns, and a separate bypass lane let northbound Trailhead traffic turn east onto Route 50 without entering the circle. The county's quarterly report put Trailhead's total budget at $14,360,579. Everfield's total project budget is $7,857,258, roughly half that figure, and the design is a single lane. Everfield is meant to be the smaller of the two.

The Long Arc Behind It

Route 50 through western Loudoun has been under a deliberate slowdown plan for a long time. Lardner/Klein, the landscape architecture firm that worked on it, describes the Route 50 traffic calming effort as a 20-mile project that started in 1995. It used village entry treatments, warning strips, raised intersections, valley gutters, distinctive paving and changes to the road's alignment to slow drivers while keeping the historic character of the villages. The firm says the roundabouts at Gilbert's Corner, where Route 50 meets Route 15, were built in 2009, and that the traffic calming work in Aldie village was finished in 2012. The Piedmont Environmental Council has listed those Gilbert's Corner roundabouts among the area's conservation successes.

The newer projects push that same approach east, toward the growing neighborhoods on the Aldie side of Route 50. Loudoun Now covered Trailhead's virtual public meeting back in 2020, when the two-lane westbound and bypass layout was first presented. Construction then ran from tree clearing in winter 2024 to westbound work that spring and eastbound work that fall. The county reported the project substantially complete on May 5, 2025. From the first public meeting to opening took more than four years.

Everfield picks up where Trailhead left off, and it is moving faster. Design and land and utility work are both marked complete in the county's latest quarterly report, and the construction contract was awarded in September.

The Calendar, as Far as It's Been Published

Here is what the county documents actually commit to. The contract gives M & F Concrete 425 calendar days to finish, counted from the Notice to Proceed. The bid document expects that notice about 30 days after the contract is signed. The county's quarterly report for April through June 2026 lists the end of construction as spring 2028. 425 days is about 14 months, which fits that spring 2028 target once the paperwork clears this fall.

One detail in that report could move the date. During the spring quarter, the design team learned that a new utility had been installed inside the project limits and might conflict with the roundabout. The county says it is still working with the utility to assess and relocate it.

None of the county documents reviewed for this post give lane closure dates, work hours or detour routes. The bid package requires a multi-phase traffic management plan but does not lay out the phases. Trailhead was built westbound first and eastbound second, but nothing published says Everfield will follow the same order.

The Overlap East of Everfield

The bottom row of that table is why the next 18 months may feel busier than any single project. VDOT's Route 50 corridor improvements project will lengthen the eastbound left-turn lane at Arcola Boulevard and add a second left-turn lane there. It will also convert the westbound inner left-turn lane at Pleasant Valley Road into an extra through lane that runs to the westbound left-turn lane at Tall Cedars Parkway. VDOT estimates the cost at $9.1 million. The project is still in design, with advertising expected in spring 2027, construction starting in summer 2027, and completion listed as "TBD." The page was last updated September 24, 2026.

If both schedules hold, crews will be working at Everfield and at Arcola Boulevard during the same months of 2027 and into 2028. The two projects also sit on very different stretches of road. VDOT counts about 18,000 to 49,000 vehicles a day within its project limits, with the heaviest volumes toward the eastern end. The Arcola work adds turning capacity at that busier eastern end, while Everfield gets a single-lane roundabout meant to calm traffic. So the same highway is being slowed down in Aldie and widened for turning traffic farther east, at the same time.

Where the Updates Will Show Up

The project pages are the most reliable way to follow what happens next:

1. The Everfield bid record on Loudoun's procurement site, which has the contract scope and award.
2. Loudoun's Department of Transportation and Capital Infrastructure quarterly reports. These will show whether the utility conflict at Everfield changes the spring 2028 date.
3. The Trailhead Drive roundabout project page, which shows how the county presented its last Route 50 roundabout to residents.
4. VDOT's corridor project page for the Arcola Boulevard and Pleasant Valley Road work.

In the meantime, the finished part of the corridor sits right in the village. Aldie Mill Historic Park, at 39401 Little River Turnpike, offers free guided tours of the merchant mill on Saturdays and Sundays from 11 a.m. to 4 p.m. through the end of October, according to the NOVA Parks weekend tours page. Its "Monroe at the Mill" program, with historian Jay Harrison portraying James Monroe, runs October 18 and November 15, 2026, from 1 to 2 p.m. Adult admission is $20 in cash, and students get in free.
