Rosales+

What Rosales+ does

Rosales+ is a Boston-based bridge design, engineering, and architecture firm that specializes in what it calls "bridges as structural art." Founded in 1997 and led by principal Miguel Rosales, the firm delivers conceptual through final design services for cable-stayed, suspension, arch, beam, and truss bridges, alongside highway corridors, interchanges, and streetscape elements. Notable proprietary structural approaches documented in the portfolio include a first-of-its-kind unbraced three-arch configuration (Licking River Bridge), a self-anchored suspension system that eliminates large anchor blocks (Tilbury Bridge), and a variable-depth box superstructure used on the I-70 Mississippi River Bridge. The firm's design work has been recognized with more than 50 awards from engineering and architectural organizations.

The firm serves exclusively public-sector clients, including state Departments of Transportation (MassDOT, Iowa DOT, Ohio DOT, Illinois DOT, Maryland State Highway), city and municipal governments (City of Boston, Greenville SC, Hickory NC), regional transit authorities (MBTA, TriMet in Oregon), and international government entities such as Panama's Ministerio de Obras Públicas. Project contract values range from approximately $1.2 million for pedestrian bridges like Evans Way to $1.1 billion for the MBTA Draw 1 Bridge vertical lift project. Revenue is generated through project-based professional services engagements secured via competitive bidding and direct procurement with government agencies; no productized pricing is publicly disclosed.

Rosales+ markets primarily through its portfolio website (rosalespartners.com), LinkedIn, Facebook, and Vimeo, with geographic reach across US Northeast, Southeast, Midwest, West, and Southwest regions plus international projects in Panama, Canada, the UK, and the UAE. The firm operates from 84 Mount Vernon Street, Boston, MA, reports a 1-10 employee headcount, and is privately held with founder-led ownership and no identified institutional investors, parent company, or funding rounds.
