How Connecticut Avenue Construction Is Reshaping Dupont Circle

For most of the past year, the block of Connecticut Avenue between Dupont Circle and Q Street has been a construction site with a very specific hole in it. That hole is gone now. As of this month, all 49 structural girders that will support the new deckover plaza are in place, ahead of the District Department of Transportation's original schedule, according to Ward 2 Councilmember Brooke Pinto's most recent briefing on the project. Crews are moving into the next phase: insulating those beams and pouring the concrete deck itself.
Most residents watching this progress assume it means the same thing: the sooner the beams go in, the sooner things go back to normal. Some changes will remain after construction.
The full project, a streetscape and deckover effort priced at roughly $37.8 million, started in the summer of 2025 and is tracking toward a summer 2027 finish. The plaza portion specifically could open as early as January 2027, ahead of the rest of the streetscape work, per Pinto's update. In the meantime, expect continued disruption: an Axios update from late July confirmed the underpass lanes are now closed overnight Monday through Thursday and all day from Friday evening through Monday morning, a closure pattern DDOT says will run for up to four months from that point.
Here's the detail that changes how you should read all of this. When the project wraps, the two service lanes on Connecticut Avenue will reopen to car traffic. Parking will not return to them. In WJLA's report on the project's groundbreaking, DDOT's chief engineer, Rick Kenney, described the intent:
"We're hoping to encourage a major mode shift of the people that patronize here."
The change reflects a broader redesign of the corridor. Some businesses have built their customer base around convenient curbside access; others have not. The project offers an early look at how the corridor will function after completion.
The businesses in the first category are having a rough year, and they've said so publicly. At a DDOT budget oversight hearing in April 2026, Bibibop Asian Grill owner Mihye Yoon told the committee plainly: "This is not a slowdown. This is a crisis." Edward Camacho of Rosemarino D'Italia testified that revenue was down 25 to 35 percent since construction started, forcing him to cut staff hours by 30 to 40 percent. Eight other business owners echoed similar numbers that day.
The Dupont Circle Business Improvement District has since reported that foot traffic on some blocks has dropped by 50 to 60 percent, and the BID has asked the D.C. Council for $2 million in relief funding to help affected businesses cover rent through construction. Taim, the falafel spot that had been a lunch-rush fixture, closed its doors this year, and Axios noted that some in the neighborhood wondered aloud whether the construction played a role.
What these businesses share isn't cuisine or price point. It's a model built on visibility from the street and easy stop-and-go access.
Set that against the restaurants that have opened or expanded in Dupont Circle in the same stretch of time, often on the same blocks affected by the same construction, alongside established businesses that remain accessible.
The list spans destination restaurants, expanded offerings, and a longstanding bookstore. Their circumstances differ, but each gives visitors a reason to come to this part of Dupont.
Another project is planned for the area. In July, the Davis Companies announced Dimora Dupont, the office-to-residential conversion of the former Ring Building at 1200 18th Street NW. The project will bring 166 residential units and 6,446 square feet of ground-floor retail, and its anchor restaurant tenant is already locked in: a new Bistro Français, paying homage to the Georgetown original of the same name, slated to open in August 2027, right after the full streetscape project itself is expected to wrap.
None of this means the neighborhood has stopped functioning day to day. The Sunday FRESHFARM farmers market is still running on 20th Street, and DDOT built its detour plan specifically around keeping that closure predictable rather than letting it collide with construction traffic. Sidewalks remain open along the corridor even where they've been narrowed, and access to businesses along Connecticut Avenue, including Kramerbooks, has been maintained throughout every phase so far.
If you're walking this stretch through the fall, expect the overnight and weekend underpass closures to continue for the next few months as beams get insulated and the deck gets poured. Expect a few more storefronts to feel the squeeze before the plaza opens, while businesses across the corridor continue to navigate construction and changing access.
Dupont Circle isn't waiting for construction to end so it can go back to what it was. It's already showing you, block by block, what it's becoming.
