McCormick Taylor is honored to be recognized with the City of Philadelphia as a 2026 American Council of Engineering Companies Pennsylvania (ACEC/PA) Diamond Award Winner. Presented on January 22, 2026 at the annual awards gala, McCormick Taylor received the award for the Penrose Roundabout Project in the Medium Projects category, which represents projects with a total project construction budget between $5 to $10 million dollars.
“Winning this award is a testament to the partnership we have with the City of Philadelphia, the coordination done early on in the project with multiple project stakeholders, the technical design expertise of our staff, and the communication and collaboration with the contractor,” said Jeannette Quirus, PE, PTOE, McCormick Taylor Director, Traffic Engineering. "I am grateful to have been able to work with such a great team to deliver this signature project."
Each year ACEC/PA celebrates the industry and recognizes projects, like the Penrose Roundabout, that “demonstrate a high degree of achievement, value, and innovation”. Projects are selected for 14 categories and one Grand Conceptor award. Projects are reviewed and ranked by a distinguished panel of industry peers and evaluated for excellence in innovation and originality; lasting value to the profession and public perception; social, economic, and sustainable development impact; technical complexity; and the successful delivery of client and owner goals.
The Penrose Roundabout Project exemplifies innovation by transforming one of South Philadelphia’s most confusing intersections into a modern, 5-leg, single-lane roundabout. The roundabout replaced a large and confusing 6-leg signalized intersection located adjacent to the elevated I-76 Expressway connecting 20th Street, Penrose Avenue, Moyamensing Avenue, and Packer Avenue. With improvements to geometry, connectivity, compatibility, accessibility, and traffic operations, the Penrose Roundabout is a model of how thoughtful, input-driven design can create safer, more sustainable streets. Building the roundabout while maintaining traffic in a temporary roundabout condition is now a model for future roundabout projects in the City. The project was completed nearly 3-months ahead of schedule and by avoiding various iterations of temporary signals, construction was simplified for all involved.
