Walk the service lanes between Dupont Circle and Q Street right now and you'll pass steel beams settled into place forty feet overhead, a jersey barrier corridor narrow enough that two people can't easily pass, and a hand-lettered sign in a shop window explaining why the register has been quiet. Walk one block over to P Street or M Street and you'll pass a soft opening, a new sign going up over an old bar's bones, and a dining room that's booked through the weekend. Same neighborhood, same month, opposite economics. That split is the actual story of Dupont Circle this August, and it's more useful to understand than either half on its own.
The Corridor Under the Cranes
The Connecticut Avenue Streetscape and Deckover project has been under construction since June 2025, and as of early August 2026 it hit a real milestone: all 49 support girders that will form the base of the new plaza are now in place, ahead of the original schedule, according to Council Member Brooke Pinto's office. Next comes insulating those beams and pouring concrete. The deckover plaza itself, the part that covers the underpass between Dupont Circle and Q Street, could be walkable as soon as January 2027, ahead of the rest of the streetscape work, though the full project isn't expected to wrap until summer 2027.
The idea for covering that stretch of underpass isn't new. Residents were calling it an eyesore back in the 1960s. What's new is that it's actually happening, at a total cost of $37.8 million, with roughly a quarter coming from the Federal Highway Trust Fund rather than the District's own budget.
For anyone walking or driving through right now, the practical detail that matters is the closure pattern. As of late July 2026, the underpass lanes were closing overnight Monday through Thursday and all day from Friday evening through Monday morning, a schedule projected to run for up to four months from that point, putting the likely end sometime this November. When those lanes are closed, the posted vehicle detour routes through 19th Street for one block and back via Q Street, with a separate bus and truck detour using Florida and Massachusetts Avenues.
Who's Absorbing the Disruption
That closure schedule sounds manageable on paper. It hasn't felt that way to the businesses sitting directly on those service lanes. At an April 2026 DC Council budget hearing, ten Dupont business owners testified about what the construction has actually done to their revenue. Edward Camacho, owner of Rosemarino D'Italia, put numbers to it: "Revenue is down 25-35% since construction started, and we've had to cut our staff hours by 30-40% due to the lack of foot traffic." The Dupont Circle Business Improvement District reported that some businesses along the corridor saw foot traffic drop by as much as 50 to 60 percent during a particularly heavy stretch of construction this past spring.
The names behind those numbers are specific and worth knowing if you live nearby. Mihye Yoon, who owns Bibibop Asian Grill, told the Council this isn't a slowdown, it's a crisis. Hua Ping Xu, owner of DuPont Lash and Brow Bar, said grant funding would at least signal the city hasn't forgotten small operators while it builds something bigger around them. Hamdu Abduselam, who runs the FH Amsterdam convenience store, has said he hasn't been able to make rent for months, in part because customers can no longer park out front and some assume the store is closed.
The city has responded with targeted, if modest, relief. The Department of Small and Local Business Development has granted $10,000 each to businesses in the 1500, 1600, and 1700 blocks of Connecticut Avenue, the same blocks where Kramerbooks and other long-standing storefronts sit. The BID is still pushing the Council for the additional $2 million in grants it requested back in April, arguing the existing support hasn't caught everyone who needs it.
Kramerbooks, at 1517 Connecticut Avenue NW, and its neighbor JF Books sit directly along the service lanes where sidewalk space has been narrowed by construction barriers. DDOT has repeatedly emphasized that pedestrian access to storefronts like Kramerbooks is maintained throughout construction, even as the walking space in front of them has shrunk. JF Books manager Can Xiong has said the narrower approach and lost street parking put the store's regular free author talks at real risk of losing the walk-up crowd that used to fill them.
One Block Over, the Opposite Story
Here's what doesn't show up in the coverage of that Council hearing: at the same time those testimonies were happening, a wave of new openings was moving into the neighborhood, mostly just off Connecticut Avenue on streets the deckover project hasn't touched.
On P Street, La Merna had a soft open in early August with a full opening the following week. A few doors down, Ko Japanese Dining has spent about two years building a following for its kaiseki tasting menu on the third floor of a converted rowhouse, unaffected by anything happening on Connecticut. Over on M Street, new signage went up in early August for Dupont Public House, taking over the old Sign of the Whale space after a GM from Across the Pond spent months getting it ready, missing an original hope of opening in time for the World Cup. District Taco added a full mezcal and tequila bar, called the Mezcaleria, inside its flagship Dupont location this year. And in May, the Austin-born sushi concept Uchi opened its Dupont-area debut, a 185-seat space built to feel specific to the neighborhood rather than a copy-paste of its other locations.
None of that is happening because the construction created an opening. It's happening despite the construction, on streets that never got torn up. That's the part worth sitting with: the same reporting cycle that produced headlines about businesses testifying for emergency rent relief also produced headlines about new restaurants signing leases blocks away. Longer-term capital appears to be reading this differently than week-to-week retail is. The clearest example is the Dimora Dupont conversion at 1200 18th Street NW, where a Boston-based developer is turning 166 units of former office space into housing and bringing Bistro Français in on the ground floor. That's a multi-year bet on the corridor's future, made in the middle of the corridor's hardest year.
What This Actually Changes for How You Move Through the Neighborhood
If you live in Dupont Circle, the useful takeaway isn't "construction bad" or "restaurants good." It's that these two stories are running on different clocks in different places, and knowing which block you're on tells you which one you're getting.
If you're trying to support a neighbor who's absorbing real financial pressure right now, that means the businesses along the Connecticut Avenue construction corridor specifically: Kramerbooks and JF Books on the service lanes themselves, and Bibibop, Rosemarino D'Italia, DuPont Lash and Brow Bar, and FH Amsterdam nearby along the same stretch. All are still open and still reachable on foot, even if the walking space in front of them is narrower than it used to be.
If you just want an evening out without dodging barriers, P Street and M Street haven't missed a beat. That's where the new openings are clustering, and it's a short enough walk from the construction zone that you can do both in one outing if you're inclined.
The weekend underpass closures are on track to run into November, and the plaza itself may be walkable by January 2027, ahead of the streetscape work wrapping next summer. Until then, the neighborhood is genuinely two different experiences depending on which side of Q Street you're standing on, and that's worth knowing before you decide the whole corridor is either struggling or thriving. It's doing both, at the same time, a block apart.
If you're thinking about what any of this means for property here, whether you already own on Connecticut Avenue or you're weighing a move to the neighborhood once the plaza opens, the Mike Aubrey Group knows this corridor block by block, not just by the headlines.
