The Dupont Circle deckover project in Washington, D.C., is approaching completion, with the city’s Department of Transportation aiming to open the new pedestrian plaza in 2027. The development will cover the existing underpass between Dupont Circle and Q Street NW along Connecticut Avenue, creating a park-like space intended to enhance the neighborhood’s public life while maintaining the roadway beneath for north-south vehicle traffic.

The $37.8 million project, supported by the Dupont Circle Business Improvement District (BID), reached a significant milestone in July with the installation of steel beams that will support the elevated plaza. The design incorporates a large ventilation opening with mesh to ensure airflow to the underpass below. The plaza will be paired with a concurrent streetscaping initiative, which includes adding bike lanes and updated sidewalks to improve pedestrian and cyclist safety nearby.

Unlike the historic and federally managed Dupont Circle park, the new plaza will be owned and maintained by the city. This arrangement will allow the BID and Historic Dupont Circle Main Streets, a local nonprofit, to organize events such as the D.C. Holiday Market, flower markets, an expanded Sunday farmers market, as well as movie nights and concerts. The space will have flexible seating areas but intentionally limited plantings to allow for diverse programming.

The deckover traces its origins to visionaries like Michael Feldstein and artist Lily Spandorf, who first collaborated on the concept nearly two decades ago. Although Spandorf passed away in 2000 and Feldstein in 2016, the project has persisted through extensive community input, a design process that involved the creator of New York City’s Bryant Park, and setbacks caused by the COVID-19 pandemic. Groundbreaking took place in 2025, and officials anticipate finishing work ahead of schedule by the end of 2026.

Despite broad support, the construction phase has prompted challenges for local businesses due to road closures and detoured traffic. Several business owners reported significant revenue declines, including a 31 percent drop for Bibibop Asian Grill in the first quarter of this year compared to last year. Some merchants have sought financial assistance from the D.C. Council to mitigate losses. However, many community members and the Advisory Neighborhood Commission remain optimistic about the project’s long-term benefits in revitalizing Dupont Circle, which had experienced a decline in vibrancy over the last decade.

“The idea is to bring back the neighborhood’s energy and restore its status as a welcoming, lively public space,” said Jeff Rueckgauer, an ANC representative. Public engagement continues as planners seek input on programming and use of the new plaza, emphasizing community involvement as key to its success.

Overall, the deckover is designed to complement rather than replace the existing Dupont Circle park, creating interconnected public spaces that serve varying purposes and attract residents and visitors alike to this historically significant Washington neighborhood.
