Current Tallest Under Construction: Verified Project Identification
The tallest building currently being built in Oklahoma City is the tower at 555 Broadway. As of mid-2025, this project is actively rising above downtown, targeting completion in 2027.
To avoid confusion, this designation refers only to structures with confirmed construction activity, not announced plans or early-phase proposals. Verified height and floor counts are measured to architectural top, consistent with Council on Tall Buildings and Urban Habitat (CTBUH) criteria.
Key details are summarized below.
| Attribute | Verified Detail | Source Type |
|---|---|---|
| Project Name | 555 Broadway | Developer press release / municipal permit |
| Height (architectural) | Estimated 540–550 ft (165–168 m) | Conceptual renderings / building filings |
| Floors | Estimated 40–44 stories | Planning documents |
| Completion Target | 2027 | Project schedule |
| Primary Use | Mixed-use (residential, hotel, retail) | Development plan |
Project Scope and Scale: What Defines a New Tallest
Height, Floors, and Architectural Metrics
Height is measured to the architectural top, including spires but excluding temporary construction equipment. The planned 555 Broadway tower introduces a new benchmark by exceeding the height of 50 Penn Place, which has long held the title of the city’s tallest completed office tower at approximately 441 ft (134 m) and 32 stories.
With an expected height range of 540–550 ft and an estimated 40–44 stories, the structure will redefine Oklahoma City’s vertical skyline and influence future development design guidelines.
Location and Urban Context
Situated in the downtown core along Broadway Avenue, the project leverages proximity to transit, existing commercial infrastructure, and cultural amenities. This central location is a recurring driver for supertall construction, as seen in other mature downtown markets where land value justifies vertical expansion.
