Organization Overview

Bowman Consulting Group welcomed McMahon Associates, Inc. in May 2022 as an addition into the firm, bringing together decades of specialized transportation expertise to support a national, multidisciplinary platform. Founded in 1976, McMahon built a strong reputation across Pennsylvania and the eastern U.S. for delivering innovative, client-focused solutions in transportation engineering, planning, and technology.

Now as Bowman, we continue that legacy with enhanced capabilities and a broader geographic reach. Bowman provides comprehensive services for transportation projects—from initial planning and traffic studies through survey, roadway/highway and bridge design, right-of-way acquisition, permitting, and construction-phase services.

We proudly serve a diverse range of public and private sector clients, including state DOTs, local municipalities, transit agencies, developers, institutions, and utility companies. Our integrated approach and commitment to quality have helped us earn the trust of clients throughout Pennsylvania and across the country.

With over 2,000 professionals in offices nationwide and a deep bench of talent across the Mid-Atlantic, Bowman is positioned to support transportation infrastructure initiatives of any size or complexity, from urban corridors to rural alignments, from multimodal access improvements to intelligent transportation systems, and beyond.
